I've always been a big believer in physiognomy*. I cannot prove it scientifically, nor do I believe it would necessarily hold up to scientific scrutiny, but it has always felt true to my experience of people. People who look nice usually seem to contain niceness. People who look mean usually seem to contain meanness.
I have never felt let down by this intuitive assessment tool, until Iranian President Mahmoud Ahmadinejad began showing up in the news. My physiognomic response to seeing his likeness is to feel deeply warm feelings towards the man, somehow seeing in the contours of his face a disarming humor, charm, kindness; there's just something about his look to which I respond very strongly positively. And yet I cognitively know that the man himself seems by all accounts to be a pretty bad man. Whether its his alleged nuclear weapon ambitions, his arguable election tampering, his brutal crackdowns on his people, his baffling denials of things like homosexuality and the Holocaust, I find little good to say about the man. And yet even still I see a photo of him, smiling or not, and I am still deceived into feeling something warm and fuzzy.
Thank goodness I rely more on logic than feeling when it comes to decision making... and thank goodness I have few decisions I need to make related to Mahmoud Ahmadinejad.
