Chronocentrism and the “End of History” Illusion
We measured the personalities, values, and preferences of more than 19,000 people who ranged in age from 18 to 68 and asked them to report how much they had changed in the past decade and/or to predict how much they would change in the next decade. Young people, middle-aged people, and older people all believed they had changed a lot in the past but would change relatively little in the future. People, it seems, regard the present as a watershed moment at which they have finally become the person they will be for the rest of their lives. This “end of history illusion” had practical consequences, leading people to overpay for future opportunities to indulge their current preferences.
I love it when
science Science provides strong evidence in favor of a relationship I have posited on this blog.
Both times, I have emphasized how one has to be aware of that cognitive bias, both personally, but also when taking decisions that have consequences for others. Being aware of one’s own chronocentric bias or that one suffers from the “End of History” illusion is especially important for policy makers:
[C]hronocentric policy making can be dangerous. The four most dangerous words of investing — “This time it’s different” — are also the four most dangerous words in the English language.
Going back to the example of the world at seven billion, if you believe we have crossed a special population threshold beyond which we will experience constant starvation and famine, you are probably willing to adopt drastic population-control policies that would curtail the freedom to have as many children as they want many people currently enjoy.
Would that be right? And how confident would you have to be that “this time it’s different” to justify a potential loss of welfare spread out over so many people?
