Feeling Like An Expert Has An Ironic Effect On Your Actual Knowledge

See on Scoop.itBounded Rationality and Beyond

Think you’re an expert on biology, literature, philosophy or anything else? Read on…

 

‘Know-it-alls’ don’t know as much as they think, new research finds.

The more people think they know about a topic, the more likely they are to claim that totally made-up facts are true, psychologists have found.

In the study, 100 people were given a general knowledge quiz about personal finance.

They were also shown a list of financial terms which were mostly real.

Mostly. But not all.

In fact, three terms were made up: ‘pre-rated stocks’, ‘fixed-rate deduction’ and ‘annualized credit’.

People who thought they were financial experts were more likely to claim they knew all about these three totally bogus terms.

Understanding Psychology Makes Economics Better

See on Scoop.itBounded Rationality and Beyond

Understanding behavior isn’t a way to justify government intervention. 

In Chapter 17 of his new book, “Misbehaving,” behavioral economics founder Richard Thaler describes a conference that was held at the University of Chicago in 1985 solely for the purpose of debating the value of the new field. That’s a pretty remarkable event – new areas of economics research usually get lots of buzz, but a special conference like that is rare. It shows that behavioral econ didn’t just generate excitement; it also generated a sense of threat. 

The threat was that of a paradigm shift. This term, coined by philosopher Thomas Kuhn, refers to the dread moment when scientists learn that up is down, black is white and everything they thought they understood about the world is wrong. Kuhn said that paradigm shifts happen when enough “anomalies” are found in the existing theory that a reconsideration becomes unavoidable. It’s probably not a coincidence that Chapter 18 of Thaler’s book is called “Anomalies.” 

The fear of a paradigm shift also explains the strong negative reactions to Thaler’s new book among certain tradition-minded economists. For example, John Cochrane, Thaler’s colleague at Univerisyt of Chicago’s Booth Business School, recently delivered along blast against behavioral econ on his blog:
