interesting readings about how we think

1. Why we can't count on the experts & experienced in forecasting (read the full article here)?

...the only consistent predictor was fame — and it was an inverse relationship. The more famous experts did worse than unknown ones. That had to do with a fault in the media. Talent bookers for television shows and reporters tended to call up experts who provided strong, coherent points of view, who saw things in blacks and whites. People who shouted — like, yes, Jim Cramer!

...Hedgehogs tend to have a focused worldview, an ideological leaning, strong convictions; foxes are more cautious, more centrist, more likely to adjust their views, more pragmatic, more prone to self-doubt, more inclined to see complexity and nuance. And it turns out that while foxes don’t give great sound-bites, they are far more likely to get things right.

This was the distinction that mattered most among the forecasters, not whether they had expertise. Over all, the foxes did significantly better, both in areas they knew well and in areas they didn’t
.

The conclusion: make a forecaster think like a fox & hold him/her accountable

2. how to make toddlers listen? (read the full article here)

Just remember their little brains react, not plan.

"For example, let's say it's cold outside and you tell your 3-year-old to go get his jacket out of his bedroom and get ready to go outside," Chatham explained. "You might expect the child to plan for the future, think 'OK it's cold outside so the jacket will keep me warm.' But what we suggest is that this isn't what goes on in a 3-year-old's brain. Rather, they run outside, discover that it is cold, and then retrieve the memory of where their jacket is, and then they go get it."

"If you just repeat something again and again that requires your young child to prepare for something in advance, that is not likely to be effective," Munakata said. "What would be more effective would be to somehow try to trigger this reactive function. So don't do something that requires them to plan ahead in their mind, but rather try to highlight the conflict that they are going to face. Perhaps you could say something like 'I know you don't want to take your coat now, but when you're standing in the yard shivering later, remember that you can get your coat from your bedroom."
