I read a blog called the Frontal Cortex by Jonah Lehrer.  Jonah generally reviews neuroscience papers and provides commentary.

Today, Jonah had a post called the Personality Paradox that talks about the neuroscience behind personality.  Here’s an excerpt from the paper, an Australian study found in Biological Psychiatry, that Jonah reviews:

Participants’ scores on Harm Avoidance, Novelty Seeking, Reward Dependence, and Persistence were tested for association with 1,252,387 genetic markers. We also performed gene-based association tests and biological pathway analyses. No genetic variants that significantly contribute to personality variation were identified, while our sample provides over 90% power to detect variants that explain only 1% of the trait variance. This indicates that individual common genetic variants of this size or greater do not contribute to personality trait variation, which has important implications regarding the genetic architecture of personality and the evolutionary mechanisms by which heritable variation is maintained.

Jonah ends the post with this comment:

And this might be why the Australian study came up empty: We’re trying to find the genes for personality constructs that don’t exist. It’s not that people don’t have personalities, or that these personalities can’t be measured – it’s that we aren’t the same person in every situation, which is what all these “tests” implicitly assume. It turns out that Shakespeare had it right all along. Just look at Hamlet – the Danish prince wouldn’t fit neatly into the categories of Myers-Briggs. He’s brooding and melancholy in one scene, and then violent and impulsive in the next. But this doesn’t seem strange to the audience. Instead, the inconsistency of Hamlet seems all too human.

This is particularly interesting for me and those that have read my book 10 Powerful Personas.  The whole premise of the book is that people show a different face of their personality depending on the context; our personality has many faces (called personas).  More than that, these personas are memetic–they have meme-like qualities and are, therefore, heavily influenced by social forces and change over time.

The paper Jonah reviews seems to lend some credence to this premise, which I think many people find intuitive.  What are your thoughts on the topic?

Check out Jonah’s post.  (And then buy my  book )

Being surrounded by good people is a blessing.

Persona: a "social mask"

I’ve met a lot of people in my short life.  Many of these people have been very successful.  They owe much of their success to their strong and magnetic personalities.

“Personality” is a complex thing.  And on the surface, our personality not only “changes” over time, but it also changes depending on context.  We shift gears according to our environment: we’re very different at work or with our college buddies or in front of a crowd.  Moreover, we’re not necessarily conscious of these shifts.  Our personality seems to have many faces.  These many different faces are called personas.

Personas are shared between people; you’ll find certain personas in more than one place.  This shouldn’t come as a surprise.  A persona is simply a cohesive package of behaviors.  And people certainly “rub off” on each other.

I find this deeply intriguing.  And over the years, as I’ve watched people, I started noticing patterns in these personas.  Specifically, I found certain personas to be especially powerful.

In my book, I highlight 10 powerful personas, personas that really stand for something and enable people to do great things. Here’s a few:

• The Artist
• The Cocky SOB
• The Helping Hand
• The Man in the Arena

I highlight these personas with a purpose, not merely for the sake of exploration.  If we learn to recognize these personas in other people, we’re more likely to be influenced by them, and therefore more likely to spread their valuable characteristics. This is a very good thing.

I’ll be announcing the release date soon–stay tuned.  Follow me on Twitter (@KevinVogelsang) for updates.

I hope you’ll check it out.  To date, this will be the most important thing I’ve done.
