What is the traditional hedonic perspective on happiness as espoused by Aristippus?

Happiness is the pursuit and accumulation of pleasurable sensations while minimizing pain — a good life means maximizing momentary bodily/sensory pleasure.

In what ways has the modern hedonic perspective shifted from its classical roots, and what has remained the same?

It has broadened beyond physical/sensory pleasure to include cognitive judgments and emotional experience (life satisfaction, positive/negative affect). What remains the same is the core idea that happiness is about maximizing pleasant experience and minimizing unpleasant experience.

How does the modern hedonic perspective suggest happiness is best understood?

As Subjective Well-Being (SWB), made up of three components: life satisfaction (measured by self-report scales asking people to evaluate their life overall), positive affect (self-reported frequency/intensity of pleasant emotions), and negative affect (self-reported frequency/intensity of unpleasant emotions).

What is the traditional eudaimonic perspective on happiness as espoused by Aristotle?

Happiness comes from living virtuously and fulfilling one's true potential and purpose (flourishing), not from pleasure-seeking.

What are the six dimensions Ryff identified as defining Psychological Well-Being (PWB)?

Self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth.

What is Emotional Well-Being (EWB) and why was it developed as a term?

EWB refers to the felt, subjective emotional experience of well-being. It was developed to capture something distinct from purely cognitive SWB (life evaluation) and purely functioning-based PWB — an emotional/experiential layer of well-being.

What are the five elements of Seligman's PERMA model?

Positive emotion, Engagement, Relationships, Meaning, and Accomplishment.

How do the PERMA elements represent an EWB perspective on happiness?

PERMA incorporates felt emotional experience (positive emotion) alongside functioning-based elements (engagement, relationships, meaning, accomplishment), giving a fuller emotional and experiential account of well-being beyond just cognitive life satisfaction.

How does Lyubomirsky break down percentage contributions of various happiness determinants?

Roughly 50% genetics/set point, 10% life circumstances, and 40% intentional activity.

How should the meaning of Lyubomirsky's breakdown be interpreted, and what are common misinterpretations?

It reflects average proportions of variance across a population, not a fixed formula for any one individual — the 40% intentional-activity slice is highlighted as the actionable part. Common misinterpretations include treating the percentages as exact for every person, assuming circumstances don't matter at all, or assuming the 40% guarantees happiness without effort.

Approximately how much time has elapsed for all of human evolution (since the earliest hominins)?

About 6–7 million years, since the earliest hominins diverged from other apes.

Approximately how much time has elapsed for Homo sapiens evolution?

About 300,000 years since anatomically modern humans emerged.

Approximately how long have Homo sapiens existed in a primarily agricultural environment?

About 10,000–12,000 years, since the Agricultural Revolution.

Approximately how long have Homo sapiens existed in a primarily industrial environment?

About 200–250 years, since the Industrial Revolution.

Approximately how long have Homo sapiens existed in a primarily digital environment?

Roughly 30–50 years, essentially one generation, since the rise of personal computing and the internet.

What defines "evolutionary success," and why is that the definition?

Evolutionary success is defined by reproductive success — the number of surviving offspring and genes passed to the next generation — because natural selection operates on differential reproduction, not on subjective well-being or experience.

What place have humans had on the food chain for the vast majority of our existence?

Humans occupied a middle position on the food chain for most of history, not the very top.

What are the advantages and disadvantages of large human brains, and their impact on social development?

Advantages include enhanced problem-solving, planning, tool use, and cooperation. Disadvantages include high energy cost and the need for premature, helpless birth (due to pelvis constraints), which led to long childhood dependency and reinforced the need for cooperative social support and childrearing networks.

Did big brains and tool/fire use distinguish sapiens from other human species?

No — other human species such as Neanderthals and Homo erectus also had large brains and used tools and fire, so these traits were not unique to sapiens.

Understand Harari's account of the Cognitive Revolution — what roles did flexible language, gossip, shared beliefs, and cumulative culture play?

Flexible language allowed detailed communication and gossip, which helped track social information and supported groups up to about 150 people (Dunbar's number). The ability to create and believe shared fictions (myths, religions, nations) allowed cooperation among unlimited numbers of strangers, and cumulative culture let knowledge build across generations.

How might the ability to generate and communicate shared beliefs have allowed humans to go from small bands to coordinating billions?

Because shared beliefs (money, religions, nations, laws) don't require personally knowing everyone involved — anyone who buys into the same story can cooperate with anyone else who does, enabling cooperation at any scale.

Distinguish physical reality from intersubjective reality.

Physical reality exists independently of human belief (rocks, rivers, atoms). Intersubjective reality exists only because large numbers of people collectively believe in it (money, nations, laws), yet it still produces real, tangible effects.

Explain how money, companies, nations, and human rights depend on shared recognition while having real consequences.

These entities only "exist" because people collectively agree to recognize and believe in them, but because so many people believe together, they shape real behavior, cooperation, and outcomes in the physical world.

Explain Harari's critique of the Agricultural Revolution, including the claim that wheat "domesticated" humans.

Harari calls it history's biggest fraud: wheat "domesticated" humans by making them work harder and settle down to serve wheat's spread, rather than wheat serving humans. Population and species-level success grew massively, but individual workload increased, diet narrowed and worsened, and disease/security risks rose — individual well-being likely declined even as the species thrived.

Explain how settled agriculture, property, hierarchy, and imagined orders changed human cooperation.

Settlement created surplus and property, which required hierarchies to manage and defend it. Imagined orders (religions, castes, laws) enabled large-scale cooperation and division of labor. These shared meanings support social organization but are culturally invented, not biological necessities.

What are the heritable effects of the factors that allowed Sapiens to dominate the globe likely to be, and where do we see examples today?

Likely cultural/behavioral tendencies rather than genetic changes, since there hasn't been enough time for major genetic evolution. Examples today include workplace hierarchies, consumerism and status competition, and tribalism or in-group/out-group identities.

What is the relative pace of genetic evolution compared to cultural evolution in Sapiens' history?

Cultural evolution has proceeded vastly faster than genetic evolution — genes have changed very little since the Agricultural Revolution, while culture and technology have transformed dramatically.

Define evolutionary mismatch and explain why there was no single uniform ancestral environment.

Evolutionary mismatch is when a trait that was adaptive in the ancestral environment becomes maladaptive or harmful in the modern environment because the environment changed faster than biology could adapt. There was no single ancestral environment because humans lived across many different climates, eras, and social structures over evolutionary history.

Apply evolutionary mismatch to food availability, movement, sleep, threat responses, attachment, belonging, social comparison, and modern work.

Food: cravings for calorie-dense food, once adaptive for scarcity, now cause overeating. Movement: bodies built for activity are now sedentary. Sleep: natural light/dark cycles are disrupted by artificial light and screens. Threat responses: stress responses built for physical danger are triggered by chronic non-physical stressors. Attachment: evolved for small stable groups, now diluted in large anonymous societies. Belonging: evolved for small tribes, now navigating large impersonal societies. Social comparison: evolved to compare to a small local group, now compares to a global social-media population. Work: evolved for varied, cooperative physical tasks, now often isolated, repetitive, and sedentary.

What is the evidence that social media constitutes a "product trap"?

Apps are engineered with unpredictable, variable rewards, notifications, and infinite scroll designed to exploit reward circuitry, driving compulsive checking (wanting) despite little enjoyment (liking) — evidence of deliberate design for compulsive use rather than incidental byproduct.

Explain why mismatch theory does not establish that ancestral life was uniformly happier or modern life uniformly harmful, and propose a change that improves fit while retaining modern benefits.

Ancestral life had its own hardships (high mortality, food insecurity, violence, no medicine), so mismatch only identifies specific traits that fit poorly with specific modern conditions, not an overall verdict on either era. A proposed fix is reintroducing ancestral-fitting elements (movement, natural light, in-person connection) while keeping modern benefits like medicine and technology — for example, walking meetings or limiting notifications while staying connected.

Historically, what has characterized cross-sectional happiness data, and how has that changed recently?

Historically, happiness followed a U-shaped curve across age, dipping in midlife and rising in older age, fairly stable over time. Recently, well-being has declined, especially among younger cohorts, flattening or reversing the traditional U-shape, coinciding with the rise of smartphones and social media.

From 2009–2017, in what age group did depression increase at the greatest rate, and what was the general pattern of change?

Depression increased most sharply among adolescents and teens (especially teen girls). More broadly, depression rose across most age groups but disproportionately among younger people compared to older adults.

How would you characterize the pattern of average anxiety by age in the US from 2020–2022?

Anxiety was highest among younger adults and tended to decrease with increasing age.

What are the three major components of reward described by Kringelbach and Berridge, and how can "wanting" and "liking" become separated?

The three components are liking (hedonic impact/pleasure), wanting (incentive salience/motivation), and learning (associations and predictions about rewards). Wanting and liking can dissociate because dopamine systems drive wanting while opioid-based hedonic hotspots drive liking — so a person can want something intensely without liking it, or like something without wanting more.

What is incentive salience, how is it related to wanting, and what role does dopamine play?

Incentive salience is the motivational "pull" or attractiveness assigned to a reward-predicting stimulus, making it attention-grabbing and desired — it is essentially the neural process underlying wanting. Dopamine release drives incentive salience and wanting, not pleasure itself.

How do we know that dopamine release is not the same thing as pleasure or happiness?

Studies show that blocking or depleting dopamine does not eliminate "liking" reactions (such as facial responses) to rewards, and boosting dopamine can increase wanting/motivation without increasing subjective pleasure ratings — showing wanting and liking are dissociable systems.

How could someone strongly want something they no longer particularly enjoy, and how does this apply to a non-drug example?

Because the wanting system (dopamine-driven) and liking system (opioid-driven) can dissociate, especially with repeated use, where wanting intensifies (sensitization) while liking diminishes (tolerance). Example: compulsively checking a shopping app or social media despite getting little actual enjoyment from it.

Why do Kringelbach and Berridge argue against a single brain "pleasure center," and what do they mean by hedonic hotspots?

Pleasure is not localized to one region but distributed across several small, discrete brain zones (hotspots) that amplify hedonic reactions when activated together, rather than one center generating all pleasure.

What are the three hedonic hotspots Kringelbach and Berridge identified, and how is pleasure organized more generally in the brain?

Key hotspots include regions within the nucleus accumbens shell, the ventral pallidum, and areas of the orbitofrontal cortex. More generally, pleasure arises from a distributed network of interconnected hotspots that must work together, with activation across multiple sites amplifying hedonic experience.

What is a personality trait?

A relatively stable, enduring pattern of thoughts, feelings, and behaviors that differs across individuals and stays fairly consistent across situations and time.

What are the "Big Five" personality traits, with a few descriptive words for each?

Openness (curious, imaginative, creative), Conscientiousness (organized, disciplined, responsible), Extraversion (sociable, outgoing, energetic), Agreeableness (kind, cooperative, trusting), and Neuroticism (anxious, moody, emotionally unstable) — remembered as OCEAN.

What associations exist between extraversion, neuroticism, and markers of well-being?

Extraversion is positively associated with well-being and positive affect. Neuroticism is negatively associated with well-being, linked to higher negative affect and lower life satisfaction.

What does the evolutionary perspective suggest about the Big Five, and what are the evolutionary advantages of extraversion and neuroticism?

It suggests these traits reflect different viable social/reproductive strategies that were each adaptive in different contexts, explaining why variation persists rather than one "ideal" personality being selected. Extraversion aids mate-seeking and building social alliances

What was the basic design of Lykken and Tellegen's study, and why are MZ/DZ twins and twins reared apart useful?

It was a twin study comparing monozygotic (identical) and dizygotic (fraternal) twins, including twins reared together and apart, to estimate genetic versus environmental contributions to well-being. MZ twins share ~100% of genes and DZ twins share ~50%, so greater similarity in MZ than DZ twins suggests genetic influence. Comparing twins reared apart versus together helps separate genetic effects from shared-environment effects — high similarity even when reared apart points to strong genetic influence.

What did Lykken and Tellegen find about the relationship between happiness and life circumstances such as income, education, SES, and marital status?

Happiness was largely independent of, or only weakly related to, these life circumstances.

What percentage of well-being did Lykken and Tellegen find to be heritable, and what percentage of the stable component of well-being was heritable?

Roughly 40–50% of well-being overall was heritable, while roughly 80% of the stable component of well-being was heritable.

What is heritability, and what does a heritability estimate actually tell us?

Heritability is a population-level statistic describing the proportion of variance in a trait among individuals in a specific population/environment that is associated with genetic differences. It tells us how much of the observed variation in a sample is linked to genetic differences given the environmental conditions present — it is not a fixed, universal, or individual-level measure.

What does it mean to say happiness is, for example, 40% heritable, and why would it be incorrect to say "40% of an individual's happiness comes from genes"?

It means 40% of the differences in happiness observed among people in the studied population is statistically associated with genetic differences. It's incorrect to apply this to one individual because heritability describes population variance, not a breakdown of any single person's happiness into genetic versus environmental portions — for an individual, genes and environment interact inseparably.

How will heritability be impacted by the circumstances in thought experiments where environments become more equal or more varied?

If environments become more uniform across a population, environmental variance shrinks, so heritability estimates go up (genes account for relatively more of the remaining variance). If environments become more varied, heritability estimates go down. Heritability is context-dependent, not fixed.

What did Lykken and Tellegen mean by a happiness "set point," and what conclusion did they draw about trying to become happier?

A stable, genetically influenced baseline level of happiness that people tend to return to despite temporary ups and downs. They were fairly pessimistic, suggesting deliberate efforts to increase happiness may have limited long-term effect since people drift back toward their set point.

What is hedonic adaptation and the hedonic treadmill?

Hedonic adaptation is the tendency to quickly return to a stable baseline level of happiness after positive or negative life events. The hedonic treadmill describes how people continually pursue new achievements or possessions for a happiness boost, but adaptation makes the boost fade, keeping overall happiness relatively constant.

Can you identify the hedonic treadmill in a vignette? Give an example.

Example: someone buys a bigger house and feels happier at first, but within months returns to roughly their prior baseline satisfaction level — that fading boost illustrates the hedonic treadmill.

What are three research findings that support the idea of hedonic adaptation?

Lottery winners' happiness tends to return close to baseline after time

How does the estimated heritability of happiness differ depending on how happiness is measured (momentary affect vs. SWB vs. stable/dispositional happiness)?

Momentary positive affect shows lower heritability

What is the difference between shared and non-shared environmental influences?

Shared environment refers to influences common to siblings raised in the same household (e.g., parents' SES, home environment) that make them more similar. Non-shared environment refers to unique experiences specific to an individual (different friends, experiences, birth order effects) that make siblings within the same family different from each other.

If studies find little effect of the shared environment, does that mean parenting, education, or poverty don't matter?

No — it means these factors don't necessarily make siblings within the same family more similar to each other, but they can still meaningfully affect absolute levels of well-being across the whole population (e.g., poverty could lower well-being broadly without creating sibling differences).

What is gene-environment correlation, including passive, active, and evocative types?

It is the phenomenon where a person's genetically influenced traits are correlated with, and shape, their exposure to certain environments. Passive: parents provide both genes and a matching environment (e.g., musical parents and a musical home). Active: individuals seek out environments matching their genetic dispositions (an extraverted person seeks social settings). Evocative: a person's genetically influenced traits evoke particular responses from others (a naturally cheerful child elicits more positive attention).

How could a genetically influenced personality trait indirectly influence a person's happiness by shaping the environments they experience?

For example, an outgoing personality (genetically influenced) leads someone to seek and build a larger social network, and those richer relationships in turn boost happiness — genes shape environment, which then shapes happiness.

How does Nes and Røysamb's view of the happiness "set point" differ from a rigid interpretation of Lykken and Tellegen?

They propose a more flexible view — the set point can shift over time due to environmental influences and life experiences, rather than being a permanently fixed target.

Does high heritability mean happiness cannot change, and how can happiness be both stable and changeable?

No — heritability describes population-level variance, not immutability. Happiness has a genetically influenced baseline tendency (stability), but that baseline can shift gradually in response to sustained environmental or behavioral changes (changeability).

What are the major "happiness myths" Lyubomirsky discusses in Chapter 2?

That happiness must be "found" somewhere external

Why might believing that happiness must be "found" be misleading?

It implies happiness is external and passively discovered, rather than something actively created and cultivated through one's own thoughts and behaviors.

Why might changing life circumstances produce less lasting happiness than people expect?

Due to hedonic adaptation — people quickly adjust to new circumstances and return to baseline, so the anticipated happiness boost fades faster and is smaller than predicted (an affective forecasting error).

What research findings disconfirm the notion that happiness set points are unchangeable?

Studies showing sustained increases in happiness following intentional activities and interventions (such as gratitude exercises or acts of kindness) contradict a rigid, unchangeable set point.

What does Lyubomirsky's discussion imply about our potential to intentionally become happier?

We have meaningful potential to intentionally increase our happiness through consistent, effortful activities, even though we can't change our circumstances or genetics — this maps onto her "40% intentional activity" argument.

Which combination defines subjective well-being?

Life satisfaction, positive affect, and low negative affect — SWB includes a cognitive life evaluation plus affective components, distinct from broader eudaimonic elements like meaning and autonomy.

A student enjoys today but believes their life is going poorly overall. Which distinction best explains this?

Positive affect versus life satisfaction — a pleasant present experience and a negative overall life evaluation can coexist as related but distinct outcomes.

A student loses track of time while absorbed in an intricate project. Which PERMA element is most directly illustrated?

Engagement — absorption indicates engagement

Why can a broadly hedonic approach include satisfaction from achievement?

Because pleasure and positive experience can arise from many sources, not only bodily sensations — modern hedonic approaches study pleasant and unpleasant experience broadly.

In Harari's account, how do shared stories expand cooperation beyond gossip?

They allow strangers to coordinate around common rules and identities — gossip helps track familiar individuals, but shared myths, institutions, and identities support cooperation among people who don't personally know each other.

A craving useful when calorie-rich food was scarce becomes problematic with constant access. Which idea does this illustrate?

Evolutionary mismatch — it concerns the altered consequences of a trait when it persists into a novel environment.

Someone repeatedly checks a shopping app despite little enjoyment. Which interpretation best fits Kringelbach and Berridge?

Wanting can remain strong while liking declines — motivational pull and hedonic impact can diverge, so continued pursuit alone doesn't establish ongoing enjoyment.

Which evidence most directly supports a causal role in core liking?

Manipulating a hotspot increases positive reactions to the same sweet taste — an experimental manipulation with an appropriate comparison supports a causal contribution, unlike mere co-activation.

What does a heritability estimate of 40% describe?

A share of observed population variance associated with genetic differences — heritability concerns variation among people in a particular population and context, not an individual decomposition or limit on change.

What did Lykken and Tellegen's roughly 80% heritability of well-being estimate refer to?

Heritability of the stable component of well-being — persistence across assessments, distinct from well-being variance in a single assessment
