There is powerful evidence against many other things now accepted as true, and often very weak evidence for them. I’d name ‘antidepressant’ pills, ‘dyslexia’, ‘ADHD’ and ‘man-made climate change’.
Those who criticize these things are angrily hushed, with righteous cries of ‘How dare you!’, and if they won’t shut up, they are punished – as was John Yudkin. Yet I believe in all these cases the critics will be proved right, as Professor Yudkin was. The miserable thing is that so much damage will be done while we wait for the truth to get the upper hand.
Be less trusting of all fashionable ideas, is my advice. Gullibility and conformity never advanced civilization by a single step.
