Two neuroscientists, Diana Tamir and Jason Mitchell, have just published an extraordinary article (Tamir-PNAS-2012) “Disclosing information about the self is intrinsically rewarding,” which speaks to the power and joys of thinking and talking about oneself. According to an interview with US News, Tamir stated “the regions of the brain that are activated by talking about oneself are also responsible for the thrills of food, sex, money and drug addiction.”
Interestingly, the media are ever-so-slightly mocking about these findings (and that’s a subject for another post):
- The Wall Street Journal: Science Reveals Why We Brag So Much
- The Globe and Mail: Why We Love To Talk About Ourselves
- The UK-based Daily Mail: The boast with the most: Bragging on Facebook ‘can feel as good as sex’
- The LA Times: Facebook, Twitter, other social media are brain candy, study says
These headlines are off-base. They disserve the real importance of the research. Tamir’s article is entitled: “Disclosing information about the self is intrinsically rewarding.” Disclosing information is quite different than “bragging” or “boasting“. Merriam Webster defines the verb to boast as “to puff oneself up in speech : speak vaingloriously.” A brag is “a pompous or boastful” statement. But when you look at the word disclose — either in dictionaries or in the actual source article itself — the meaning is distinct and does not carry a negative quality to it.
Apparently 30% – 40% of human every day speech ”is used to relay information to others about one’s private experiences or personal relationships….” The purpose of Tamir’s research was to test the hypothesis that humans are motivated to share beliefs and knowledge about the world, and therefore “opportunities to disclose one’s thoughts should be experienced as a powerful form of subjective reward.” That is, there is we should feel really good when we do self-disclose to encourage us to do it more. Tamir and Mitchell sought to find empirical support — and they found it.
[T]he tendency to broadcast one’s thoughts and beliefs may confer an adaptive advantage in individuals in a number of ways: by engendering social bonds and social alliances between people; by eliciting feedback from others to attain self-knowledge; by taking advantage of performance advantages that result from sharing ones’ sensory experience; or by obviating the need to discover firsthand what others already know, thus expanding the amount of know-how any single person can acquire in a lifetime. As such, the proximate motivation to disclose our internal thoughts and knowledge to others around us may serve to sustain the behaviors that underlie the extreme sociality of our species.
