Inferring Personality From Email Addresses

paleshadows writes "Three researchers from the University of Leipzig published an interesting paper titled 'How extroverted is honey.bunny77@hotmail.de? Inferring personality from e-mail addresses' (PDF). From the abstract: 'Email addresses represent the thinnest slice of information that people receive from one another. Using 599 e-mail addresses of young adults, their self-reported personality scores and the personality judgments of 100 independent observers, it was shown that personality impressions based solely on e-mail addresses were consensually shared by observers. Moreover, these impressions contained some degree of validity. This was true for neuroticism, openness, agreeableness, conscientiousness, and narcissism but not for extroversion."'

Next: scientists discover that how you look and act reflects on your personality, too.

Bollocks. The correlations are weak, at best, and are barely distinguishable from chance. E.g., Consider Table 2. There are 196 entries in the top section of the table. The excess of postive correlations over negative corrlations is a grand total of 8. Assuming 50/50 odds, that excess will happen about 11% of the time just by chance alone. When you factor in the conditional probablity of publishing results (i.e., the argument that if they were any weaker, the data would never have been published), this has to be an extraordinarily weak finding.

The average correlation (without regard to sign) in the same section of Table 2 is a whoppping 0.067, suggesting an average explanatory power on the order of 0.5%. I suppose such power might have some benefit to someone that sends a lot of e-mails to random addresses like spammers, but for the odinary Joe or Jo, this is not a lot to go on.

Bad example?

So the article summary starts with:
How extraverted is honey.bunny77@hotmail.de? Inferring personality from e-mail addresses

And ends with:
Moreover, these impressions contained some degree of validity....but not for extraversion

So the only example in the summary is wrong. And you can tell by reading the summary. Bravo.

In other news... another irrelevant study!

it was shown that personality impressions based solely on e-mail addresses were consensually shared by observers.

... So someone paid one hundred observers and who knows how many research administrators to find out that if a group of people look at the same word(s), they will have a similar reaction? Strange, I thought that was the primary purpose of language. Silly me...

Moreover, these impressions contained some degree of validity.

And this says absolutely nothing. At all. "Some degree of validity" includes such conditions as "My father's, brother's, nephew's, cousin's, former roommate felt that way".

How extraverted is honey.bunny77@hotmail.de

My first thought was "spammer". I suspect that says more about me than the owner of the email.

why don't you email him

and ask.
