I'm not sure a person needs a biology degree to be interested, though! IMO interesting stuff can happen when people without technical degrees start messing with new technologies in their basements...now when I look at debates like GMOs, I refrain from jumping to any conclusion.
I will certainly try to emulate this. I have noticed a tendency to kneejerk-react the same way as the rest of my tribe in my media echo-chamber :/
That's true! Having an interest is a good thing as long as people recognize their own limits. When faced with information supporting a counter view, tinkering in the basement or doing some personal research should be encouraged. Your tribal analogy is a great one. That's a better way of summarizing my block of text above: seeing the tribal responses on both sides of a debate I understood well suggested tribal responses are likely occurring in areas I don't understand well.
