INTRODUCTION

English translation pending.

CORE DEFINITION

Motivated reasoning describes the process by which people arrive at the conclusion they want and then construct support for it, rather than evaluating evidence impartially. Prior beliefs shape which evidence is sought, how ambiguous evidence is read, and how contrary findings are discounted. The drive is to protect self-image or group identity rather than to reach the truth, and greater cognitive ability tends to produce more sophisticated justifications rather than more accurate conclusions.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Name the position: state the conclusion you are hoping to reach before reviewing any evidence. - Attack your own case: assign yourself the role of opposing counsel and press the strongest objections. - Separate wanting from evidence: label each reason as something you want or something the data supports.

Reasoning serves a social and identity function as well as an epistemic one, so a conclusion that threatens identity triggers defensive processing. Evidence is then sought selectively and read in the direction that protects the prior position, while counterevidence meets standards it cannot satisfy. Greater ability improves the quality of the defense without changing its direction.
