How much information do you need to make up your mind? Our research in various domains of decision making shows that we make decisions more quickly and based on less information than we think. This has important implications in an age in which information is plentiful.
Heuristics play an important role in daily judgments and decision-making, but a scientific debate has been ongoing as to whether heuristics result in systematic errors or make us smarter. Both approaches have resulted in tools to support decision-making. Nudges address systematic errors and biases, while boosts support informed decision-making under uncertainty. But can these two opposing approaches be integrated into one framework?

Stocks yield much higher returns than bonds and other riskless securities. In fact, in the last 100 years US equities have seen an 8% average annual real return, compared to only a 1% return for more riskless securities. This gap is called the equity premium puzzle – why are equities valued so much higher than securities? One behavioral theory attributes the equity premium puzzle to what’s known as myopic loss aversion (MLA) – the idea that loss-averse investors (as all investors are) take too short-term a view of their investments, leading them to react overly negatively to short-term losses. We designed the first natural field experimental evidence to show that MLA exists for professional traders.
