Its truly an enigma - the human mind. And what is more enigmatic is the kind of conclusions it jumps to on the occurrence of an event.
The event I'm gonna deliberate about is a talk over the telephone with an unknown somebody.
Now how quickly does the mind manage to carve out a picture/sketch from the tone of a stranger? Well! my mind does it in about 25-30 seconds of talk....
Some observations:
1. The sketch generally reminds you of a known somebody
2. The accent generally defines Mr./M(r)s. X's ethnicity. Now this vaguely determines the colour of his/her skin
3. The sharpness of the tone is considered by the mind as an indicator of age
4. The type of tone contributes certain facial expressions to the sketch. For eg: A humourous conversation would create a sketch with "happy" facial expressions (smile, chuckle, twinkle in the eye, etc)
5. The type of conversation would also add/subtract certain "accessories" onto the face - an academic conversation would add say, spectacles onto the mind's picture.
Now for the moot question - How perfectly does the mind's picture concur with the real person. Ahem! well, for me in 90/100 cases, the picture is almost a perfect contrast.
Its amazing how you create an "impression" of somebody and in real time he/she turns out to be completely different. This happens not only when you converse with an unknown person but also when you read somebody's writing. Somehow, you're left disappointed most of the times. A great writer may have a very weird (I know its a subjective term) face. A blunt, straight forward conversationist may look like the most affable of people.
Somebody said - Looks can be deceptive. But why would they ever be so? Coz the enigmatic grey cells like a computer database list down assumptions as if they were a rule.
Maybe the look/tone/literature wasnt deceptive in the first place....maybe it was the mind's single-track thinking....maybe!
