In response to the article in the OP...
Certainly, I think I often naturally use the approach that is suggested to get people to like my idea. Finding out the persons objections often allows for their irrational objections to get sorted out and overthrown! Really, when used very deliberately this sort of "method" can easily be seen as manipulation. If it is used along with the rational logical facts it might be ok, but con artists use this sort of methods with spades.
I sure use a heavy dose of the logic too, and with some people that actually works!!
Many smart women use this idea with their husbands all the time - if they point the conversation in particular directions, etc, their husbands believe they have come up with the idea themselves!
There is one boss at work though who if he likes you, he will "hear" your arguments favourably, but if he doesn't like you he will dismiss the same arguments and see them negatively. I therefore thinks he is an F (but more than likely belives himself a T). I think this is a very poor way to be as a boss. The good bosses carefully balance the arguments of others and works out the logic for themselves, irrespective of whether they personally like the person (as long as they respect the person for their competence). I assume these bosses are T's.
Another thing I thought when I read the article is that TP's are frequently not as in touch with their emotions and also are known for their reticence in making decisions, making me wonder if their is a link there. However, the TJ's have no issues with this and are not necessarily any more in touch with their emotions? or are they?
