Decision Making

Obstacles to Decision Making

Overview

  • Decisions are often influenced by several cognitive biases and heuristics.
  • Obstacles can lead to poor judgments and decision-making.

Availability Heuristic

  • Definition: A cognitive bias where individuals base decisions on immediate examples that come to mind.
  • This often involves recent news events or memory.
  • Examples:
    • If a person sees news reports about a plane crash, they may decide to cancel their upcoming flights due to fear.
    • Notable case: The SARS outbreak, H1N1 flu, or the coronavirus; frequent media reporting creates a sense of alarm and perceived commonality of events.
    • Summer of the Shark example, where media coverage inflated public fear of shark attacks, leading individuals to avoid swimming due to the perception of heightened danger, despite statistics showing fewer shark attacks than previous years.
  • Implication: Decisions may be based on misleading information, leading to fear-based behaviors.

Representativeness Heuristic

  • Definition: A cognitive bias where judgments are made based on the perceived typicality or stereotype of a category.
  • Examples:
    • Deciding who likely attended Harvard based on appearances; the misconception that someone dressed more formally (like Joe Biden) is more likely than someone who does not fit that mold (like Sonia Dara, a model with an economics degree).
    • Trusting a little old lady as a nanny over a younger person based on stereotypes, despite possible capabilities of the latter.
    • Choosing a kindergarten teacher based on preconceived notions of who fits that role best based on appearance rather than actual qualifications or skills.
  • Implication: Prototype-based decisions can lead to erroneous assumptions and poor choices.

Framing Effect

  • Definition: The way information is presented can significantly influence decisions.
  • People tend to make different decisions based on how data is framed.
  • Examples:
    • Choosing a ground beef package labeled as “75% lean” versus “25% fat”; the former is more appealing as it avoids the negative connotation of fat.
    • Marketing strategies that use framing can mislead consumers, such as promoting a deal that seems beneficial (e.g., "Two for $5") when the regular price is close to that, leading consumers to believe they’re saving money.
  • Implication: Decisions may be influenced more by presentation rather than by facts.

Overconfidence Bias

  • Definition: When individuals believe they possess superior abilities or knowledge compared to others.
  • Examples:
    • Parents warning children against texting and driving, yet they may engage in the same behavior, convincing themselves they are better drivers.
    • General misconception that multitasking can be effectively managed, leading to dangerous situations.
  • Implication: Overconfidence can lead to risky and illogical decision-making.

Confirmation Bias

  • Definition: The tendency to search for, interpret, favor, and recall information in a way that confirms one’s preexisting beliefs.
  • Examples:
    • Individuals with strong political opinions often only consume media that reinforces their views (e.g., conservatives favoring Fox News, liberals favoring CNN) without exposing themselves to opposing viewpoints.
  • Implication: Confirmation bias limits understanding and receptiveness to alternative arguments, hindering rational decision-making.

Fixation

  • Definition: The inability to see a problem from a new or different perspective, often resulting in a failure to find a solution.
  • Examples:
    • A teacher unable to turn on a projector only relying on a remote, ignoring the physical power button on the device.
  • Implication: Fixation limits creativity and problem-solving abilities.

Functional Fixedness

  • Definition: A cognitive bias that prevents individuals from using an object in a new way outside its traditional function.
  • Examples:
    • Difficulty in using an alternative object (like a rock) to achieve a task (driving a nail) instead of using the conventional hammer.
    • Candle-Mounting Problem: Suggested solution involves creative thinking; using a matchbox (removing matches) as a holder to mount the candle to a board by tacking the box, rather than using it for its intended purpose.
  • Implication: Functional fixedness can obstruct innovative solutions to problems.

Belief Perseverance

  • Definition: The tendency to maintain a belief even when presented with evidence to the contrary.
  • Examples:
    • Individuals refusing to acknowledge features of Android phones despite opposition to their iPhone preference.
    • The persistent belief regarding President Obama’s citizenship even after presenting a valid birth certificate.
  • Implication: Maintaining beliefs despite contrary evidence can obstruct rational thinking and decision-making.
