Task switching is hard because we do not control what is on our mind. Despite our efforts, the original task continues to occupy our mental bandwidth. Although we can control where our time goes, we cannot fully control how our bandwidth is allocated.
If you send out one coupon with a deadline of a week and another that must be used within the next month, you end up having more redemptions with the one week deadline. It's really amazing. With the month deadline you have four times as much time, but people tend to say they'll use it in a few weeks' time and then they don't do it.
If women's choices - such as taking time off to rear children - make them less productive in the economy, does adolescent boys' behavior in school make them even less so, because they are missing the educational potential of their formative years?
Busy people all make the same mistake: they assume they are short on time, which of course, they are. But time is not their only scarce resource. They are also short on bandwidth. By bandwidth I mean basic cognitive resources - psychologists call them working memory and executive control - that we use in nearly every activity.
Time can be dissected easily: an hour can be cut up in many ways. Fifteen minutes on this memo, a five-minute walk to another meeting, 30 minutes at that meeting and then 10 minutes debriefing. Oh, and maybe a quick phone call on the walk to that meeting. The busy are expert at dissection: that's how they make it all fit.
For somebody for whom they're going to buy a certain amount of gas irrespective of the price, should they really spend so much time thinking about the price of gas? It doesn't affect anything they do.
Things that price at $4.99 sell very differently than things that price at $5.
People go shopping, we spend on so many things, and we just don't know. We don't know the prices of things. But gasoline, even when you're not buying, it's staring you in the face. Psychologists call this 'salience.'
You and I can be busy, and we take a vacation from work. You can't take a break from being poor. You can't say, 'Hey I've had enough of worrying about money, I'm just going to be rich for a couple of weeks until I've recovered.'
You can get pictures into what people are sort of thinking about others. Just go onto Google and type 'Why are Indians' and then look for the autocomplete.
Maybe poverty is a special case of something else. That something else is 'scarcity,' and anyone who has the experience of 'having very little' experiences the same psychology.
I worry about growing income inequality. But I worry even more that the discussion is too narrowly focused. I worry that our outrage at the top 1 percent is distracting us from the problem that we should really care about: how to create opportunities and ensure a reasonable standard of living for the bottom 20 percent.
Organizations talk about spending their lives firefighting - dealing with the next problem without having the bandwidth to deal with what is down the pipeline. I think most of the poor have that problem.
Our soft hearts are what tell us that, whatever the circumstances of birth, everyone must be given opportunities to do well.
