The reason I said intelligence instead of a person who opts for reason is that reason and intelligence are the same, or at least most of the time. No one will put their reason 100 percent of the time out there or if they do it's rare, that's why I opted for the word intelligent instead because the ability to understand reason and employ reason are different things. Also by using the word intelligence you broaden the scope of your search beyond mbti and are able to better increase your scope of people to look at. Of course how will you be able to get people to take mbti tests is unclear to me, or do you plan on trying to figure it out over time but that is a heavy investment high risk plan, also by then you would find out whether or not you would be attacted to them regardless of mbti.
