　　"Money spent on research is almost always a good investment, even when the results of that research are controversial."

　　I agree with the speaker‘s broad assertion that money spent on research is generally money well invested.

Research is also the chief means by which we humans attempt to satisfy our insatiable appetite for knowledge, and our craving to understand ourselves and the world around us.
