Do we have free will?
“… much of the debate about free will centers around whether we human beings have it, yet virtually no one doubts that we will to do this and that. ” Source Stanford Encyclopedia of Philosophy
Most people feel that they definitely do have free will, but the more research is performed, the harder it gets (for theorists at least) to maintain certainty.
“The notion that we have free will - the ability to exercise conscious control over our actions and decisions - is deeply embedded in human experience. But the more we learn about the physical universe and the human brain, the less plausible it becomes” source: New Scientist
