Which of the following is NOT a significant feature of an attitude?

The correct answer is Option (2) → Rationality

Option (1) Valence — A feature (Incorrect). It tells whether an attitude is positive or negative towards the attitude object, such as rating nuclear research 4 or 5 on a 5-point scale.

Option (2) Rationality — Not a feature (Correct). Rationality means being based on reason. Attitudes may or may not rest on good reasons, and it is not one of the four features by which attitudes are described.

Option (3) Multiplexity — A feature (Incorrect). Simplicity or complexity (multiplexity) tells how many attitudes there are within a broader attitude, like members of a family.

Option (4) Extremeness — A feature (Incorrect). It tells how positive or negative an attitude is; ratings of 1 and 5 are equally extreme, only in opposite directions.
