What are the hindrances in scientific inquiry?
First of all, your own mind. By education, upbringing, cultural mores, etc you have tended to see the world in a framework familiar to you. Scientific inquiry requires that you do not carry any preconceived notions before setting out to answer questions. Subsequently, there’s peer pressure. You might have a plausible answer or idea, but social and emotional pressure brought to bear by having to conform might lead to abandon your line and train of thought.
