Measuring Attitude: Scales & Tests

Explicit Measures

Likert scale: rate agreement, numbered scale

Semantic differential: rate between opposite adjectives

Implicit Measures

Implicit Association Test (IAT)

Infers attitude from reaction time, automatic bias

Measurement Limits

Social desirability bias skews self-reports

Question wording and scale format shift results

Two lenses, sometimes two different pictures

Implicit measures sometimes reveal attitudes that differ from what a person consciously reports — raising real questions about which one better predicts actual behaviour.

Must Know

• Psychologists use standardized psychological instruments to measure attitude, allowing comparison across individuals and over time.
• The Likert scale, a common attitude-measurement tool, asks respondents to rate agreement with statements on a numbered scale.
• The semantic differential scale measures attitude by asking respondents to rate a concept between pairs of opposite adjectives, like good-bad or strong-weak.
• Implicit attitude measures, including the Implicit Association Test, aim to capture attitudes people may not consciously report or even recognize in themselves.
• Explicit attitude measures rely on direct self-report, while implicit measures infer attitude from reaction time and automatic associations.

Good to Know

• Self-report measures can be affected by social desirability bias, where respondents answer in ways they believe are more socially acceptable.
• Implicit measures sometimes reveal attitudes that differ from what a person consciously reports, highlighting a gap between explicit and implicit attitude.
• Survey design choices, including question wording and scale format, can meaningfully affect the attitudes researchers measure.

Great to Know

• The gap between explicit and implicit attitude measures raises important questions about which better predicts actual future behaviour.
• Reliable attitude measurement matters directly for public administration, informing everything from policy design to public communication strategy.
• Understanding measurement limitations helps prevent overconfidence in survey results that may not fully capture genuine underlying attitudes.
