A charitable interpretation of what he said is that we need to do real world experiment instead of of relying on the opinion of supposed experts. Real data based on well made experiments trumps the opinion of any particular person.
I mean, should we be charitable when confronted with pure nonsense?
Research on education, cognition, memory, and learning is definitely much more
> Real data based on well made experiments
and not just
> relying on the opinion of supposed experts
I don't think it's acceptable to throw your hands up and say 'no one knows' when clearly people have spent entire careers thinking about this stuff and testing it in experiments, and plane-scale educational techniques. We're far closer to 'knowing' than at any point in history, and true knowing is a philosophical topic anyway without a satisfying 'answer'.
