The Associative Machine

Chapter 4 is ground zero for the book’s collision with the replication crisis. Kahneman presented social priming findings (Florida Effect, money priming, Lady Macbeth Effect) as established science. All three have since failed replication. Kahneman acknowledged this in a 2012 open letter. Cognitive priming remains valid, but the behavioral extensions are not.

So what

This chapter is the book’s biggest liability. Three of its four showcase studies have failed replication. If you read this chapter, mentally redline the Florida Effect, money priming, and Lady Macbeth Effect. Cognitive priming (word associations) is real; the dramatic behavioral claims are not.

Cognitive and perceptual priming -- seeing 'DOCTOR' speeds recognition of 'NURSE' -- demonstrates that associative activation is a real and automatic cognitive process.
