Beliefs, Evidence, and Measurement Concepts

Flashcards cover key ideas from the notes: operational definitions, alignment of beliefs with evidence, worldview, nervousness as a measure, and the role of anecdotes and anecdotal evidence.

Operational definition

A measurable, observable definition of a concept (e.g., how well someone scores on a test) to turn abstract ideas into data.

Beliefs vs. evidence

The tension between what a person believes and what evidence shows; beliefs should be weighed against empirical data, not just maintained to fit a worldview.

Worldview

An individual's overall perspective or set of assumptions that shapes how they interpret information and evidence.

Nervousness as a construct

A measure of anxiety or fear around feared stimuli, often quantified to study its relation to behavior.

Anecdotal evidence

Evidence based on personal experiences or isolated examples rather than systematic data, which may not generalize.

Chick-fil-A anecdote

A personal, illustrative story (e.g., long wait times) used to make a point, not representative of broader trends.
