This is not entirely true. Daniel Kahneman wrote about it if you want a source. Humans generally have two ways of thinking: Type 1 and Type 2. Type 1 is fast, heuristic-based, and not always accurate. Arguably, that's why things like racism and bigotry take hold. Type 2 is slow, analytical, and what lets us do things like send men to the Moon or write large software applications. The trouble is that you have to consciously shift to Type 2 thinking, it takes longer, and it's tiring. Dave Snowden of Cynefin fame has a great bit (paraphrasing here) about the purely Type 2 thinker in ancient days on the African savannah getting eaten by a lion. Because he or she sits there doing a complex analysis of "OK, felid, yellow fur, moving towards me, etc. etc." while the Type 1 thinker goes "Oh shit! Lion!" and runs away. Type 1 thinking has a role. You just have to be mindful about when you're misusing it.
