I must have taken it hundreds of times in the past couple of years (just internet tests, not the official one). For ages I was an INFJ in denial. I wanted to be a different type. Sometimes I still do.
Probably more than three times over the years.. However I picked the funny choice. In polls if there is a funny choice added... I almost always go with it..
Definitely over three times, especially if you include cognitive function tests. I found it to be pretty inconsistent, but INFJ still seems like the best choice.
I've taken the internet version at least three or four times. I agree, after that, there's no point in taking it again. I would really want to take the actual one. *ponders*
