There is still a great deal of research being done by amateurs, particularly in biological field observations, agriculture, anthropology, archaeology, and astronomy, where the professionals simply can't get to all the opportunities on their own. There are also several branches of mathematics, such as combinatorial game theory, where amateurs like Omar, Our Most Assiduous Reader can make significant contributions.

On the other hand, poverty does not mean that they lack intelligence. The Andaman Islands had nearly no loss of life in the tsunami because the tale had been passed down over many generations that you had to run for high ground any time the sea went away. That's science.
