i would like the help of the people on this forum because i am in the middle of drawing the character that represents pseudoscience.
Okay, call me sexist if you must, but I think that the "pseudoscience believer" archetype would best be captured by an image of a female. That guy you've drawn has too much of a "startled pizza maker" and not enough of a "homeopathic palm-reader" vibe to him.
Actually, I think the problem is that there isn't one stereotype. You have the granola-munching hippie energy types, the patriotic republican god-is-on-our-side types, the feminist pagan politically correct types, the lives-with-his-mother conspiracy theorist types, etc. There's so much woo you can't boil it down to just one type.
And then there's the sincerely stupid (Deepak Chopra) vs. maliciously evil (Kevin Trudeau) types.
The character you've drawn looks to me most like the conspiracy theorist. He'd have something on his shirt about "The Truth Is Out There," or "C'mon Sheeple, Open Your Eyes!" or something of that nature.
