This is a fantastic clip from an American version of “Dragon’s Den” which I think would make an excellent starting point for a discussion on “how science works”. It’s so good it could have been made for this very purpose:
Some obvious questions to get the discussion going:
Are the Dragons right or are they just being rude by refusing to allow the guy to show them more of his “research”? (He claims to have lots more he can show them)
What, if anything, is wrong with the salesman’s research?
The salesman claims he has video testimony of people who have been cured by his medicine – would that be enough to convince you of its efficacy? If not, why not?
Why do you think the “Dragons” reacted so violently against this man?
