I've always had a very easy time understanding science as long as I stuck to books, pencil and paper, periodic table, etc.... As soon as I start using my hands (like in a laboratory setting) things start to go wrong. I have a tendency to break things: beakers, flasks, crucibles, etc.... If I ever did "real scientific research" (i.e. in a laboratory), then I'd need an ISTJ assistant to meticulously do all the hands-on work, so I wouldn't blow us all to kingdom come.
