If there were Weirdness Olympics between all 16 types then INTj would be an unbeatable gold medallist. In fact INTjs are so weird that they do not just appear weird to people who don't know them, but to other INTjs as well. This is because INTjs take little or no notice of what other people think. What they think themselves is much more important to INTjs. That is why if everybody is certain that bridges have to be built across the river, an INTj may contemplate the possibility of building one along the river. There would probably be a logical reason for that since INTjs view everything through the square prism of logic. And as long as logical rules are obeyed everything is fine.
btw, obviously the solution is to build a bridge along the river, after all the problem is that people are complaining about muddy boots!
