Your PFC is the latest and most updated architecture in your brain's evolution. 

What exactly does your PFC do?

- Do the harder decision

It is a simulator. 

a trio of researchers at Northwestern University and the University of Massachusetts attempted to answer this by asking two very disparate groups about the happiness in their lives: recent winners of the Illinois State Lottery — whose prizes ranged from $50,000 to $1 million — and recent victims of catastrophic accidents, who were now paraplegic or quadriplegic. In interviews with the experimenters, the two groups were asked, among other things, to rate the amount of pleasure they got from everyday activities: small but enjoyable things like chatting with a friend, watching TV, eating breakfast, laughing at a joke, or receiving a compliment. When the researchers analyzed their results, they found that the recent accident victims reported gaining more happiness from these everyday pleasures than the lottery winners.


This is how the study is usually written about, in a “gee whiz, ain’t that counterintuitive?” kind of tone. But what’s really striking when you look at the results reported by the researchers is how close their answers actually are: On average, the winners’ ratings of everyday happiness were 3.33 out of 5, and the accident victims’ averaged answers were 3.48. The lottery winners did report more present happiness than the accident victims (an average of 4 out of 5, as compared to the victims’ 2.96), but as the authors note, “the paraplegic rating of present happiness is still above the midpoint of the scale and … the accident victims did not appear nearly as unhappy as might have been expected.”


This is partially because of what’s become known as the hedonic treadmill, or hedonic adaptation, that annoying tendency humans have to get used to the things that once made them happy. I particularly love how the authors of this 1970s paper phrased it:


Eventually, the thrill of winning the lottery will itself wear off. If all things are judged by the extent to which they depart from a baseline of past experience, gradually even the most positive events will cease to have impact as they themselves are absorbed into the new baseline against which further events are judged. Thus, as lottery winners become accustomed to the additional pleasures made possible by their new wealth, these pleasures should be experienced as less intense and should no longer contribute very much to their general level of happiness.

So this means that anything shiny and new in life — like a job, or a sweater, or a spouse — is exhilarating, until it becomes the thing we get sick of seeing every damn day. Likewise, some psychologists have theorized that people have a happiness set point, a baseline level of well-being preprogrammed by our genetics and further shaped by our environment. This theory suggests that the emotional aftermath of wildly fantastic strokes of luck or devastatingly catastrophic calamities will essentially leave you just as happy as you ever were. (Though some recent research has poked a few holes in this line of thinking.)


But maybe the most important thing this research has to suggest is just how awful people are at predicting what will make them happy, something psychologists call affective forecasting. This is perhaps particularly true when it comes to money: A shorter commute would make you as happy as a 40 percent raise, getting a paid vacation from your boss would make you happier than receiving cash, and having more free time will make you happier than having more money, and yet people often guess that more money is the answer.
