Because you have used the word arrogant, it seems that you have concluded that at least some science are failing to recognize possible valuable contributions from non-scientists.
I don't think that's really the issue...it's not the ability of the ignorant to contribute, but rather that their curiosity be allowed to flourish. which could lead to greater contribution.
As an example, let’s examine my feelings toward math. If I understand it, and can properly perform it, I find it cool, and even fun. But when I lack the understanding, and a 30 minute equation turns into 2 hours, it's frustrating and exhausting. It's difficult to find proper tutors or capable students to study with. That is part of the reason why I've returned here.
I think curiosity is a powerful driving force, and when given enough prodding to flourish it can lead to great discovery, and great scientists, and great interest. What will it take though, a change in public approach, a change in the educational system, or a shift in society’s mainstream media, orwhat?
keep your mind from this way of enquiry, for never will you show that not-being is
