How and more importantly why does the placebo effect works?
The placebo effect is a long-recognised phenomenon that has played an important part in the history of medicine — from the healing powers of Stonehenge to administering placebo drugs to modern day patients. But it’s not until recently that science has begun to truly understand how the placebo effect really works.
Professor Nicholas Humphrey asks why placebos work and reveals their central paradox: If we can effectively cure ourselves by taking placebo medicine, why don’t we just heal ourselves straight away?
Exploring this paradox from the perspective of evolution, Professor Humphry looks at the associated costs and benefits of pain or illness. How can placebo medications readdress this balance and is a “dose of contrived optimism” just what the doctor ordered?

In a talk full of humor, he shows how you can’t hope to understand humans as separate individuals making choices based on their conscious awareness.
This a video from TedEd about the psychology of learning and the difference between classical and operant conditioning.
Why is it that humans react to stimuli with certain behaviors? Can behaviors change in response to consequences? Peggy Andover explains how the brain can associate unrelated stimuli and responses, proved by Ivan Pavlov’s famous 1890 experiments, and how reinforcement and punishment can result in changed behavior.

Can we use science to be more productive ?
In today’s crazy world, productivity is on the minds of many. So what can science tell us about the human brain and productive work? How do we become more efficient at working, and spend less time working overall?
