To encourage people to associate with us, we want to seem principled, with a stable permanent nature. We want this nature to seem attractive and to fit with our community’s social norms, we want it to be associated with high status, and we want it to fit our personal situation and preferences. However, community norms and status rankings often change, and we often participate in overlapping communities with different norms. So we need to be able to change our nature and norms, to adapt to changing conditions. Yet we also want such changes to feel authentic, and not consciously or overtly done just to accommodate neighbors. How can we accomplish all these goals at once?
One simple strategy is to have a stable personality, but to sometimes let impressive high status people move us to change that personality. When we hear someone express an opinion, directly or indirectly, we evaluate that person and their expression for impressiveness and status. The higher our evaluation, the more receptive we let ourselves be to the emotions they express, and the more plastic we become at that moment to changing our “permanent” nature in response.
In this way we can limit our changes, yet still track changing norms and status. We become like metal that is forged by heat; we usually have a solid reliable shape, but we let ourselves be reshaped by the rare heat of great impressiveness. Some recent evidence suggests that we in fact do this:
In one experiment, … psychologists … randomly assigned participants to one of two groups: one whose members read .. [a] short story centered on marital infidelity, and another whose members read a “nonfictionalized” version of the story, written in the form of a report from a divorce court. The nonfiction text was the same length and offered the same ease of reading. … It contained the same information, including some of the same dialogue. (Notably, though readers of this text deemed it less artistic … they found it just as interesting.)
Before they started reading, each participant took a standard test of the so-called big five personality traits. …. Then, after … were again given the personality test. … The personality scores of those who read the nonfiction text remained much the same. But the personality scores of those who read the … story fluctuated. The changes were not large but they were statistically significant, and they were correlated with the intensity of emotions people experienced as they read the story. …
Another experiment … asked participants to read one of eight short stories or one of eight essays. Essays … average length, ease of reading and interest to readers were the same as those of the stories. … We had expected that people who read a piece of fiction would experience the greatest fluctuation in their personality scores, but we didn’t find this. The genre of the text — fiction or nonfiction — didn’t matter much; what mattered was the degree of perceived artistry. Those who read a story or essay that they judged to be artistic changed their personality scores significantly more than did those who judged what they read to be less artistic. (more)
Fluctuations in personality comparable to those that occurred in reading artistic literature have been found when people listened to music (Djikic, 2011) and looked at pieces of visual art (Djikic, Oatley, & Peterson, 2012). These results support the hypothesis that literature shares with other arts an effect of introducing a perturbation to personality, which can sometimes be a precursor to a more permanent personality change.

I agree with the point of this think-tank essay for the most part
Yes of course that better studies would look at longer timescale effects. I report on the studies I see.
