However, I think they should come with a safety notice. Warning: Some celebs may be idiots.
This week an American basketball star has joined other famous people by saying he believes the Earth is flat. NBA star Kyrie Irving said in a podcast, "This is not even a conspiracy theory. The Earth is flat. I'm telling you, it's right in front of our faces. They lie to us."
It's tempting to reply to that with points about how, if the Earth was flat you'd be able to see out to sea a lot further, a new moon would have a square-edge shadow of the Earth on it, and sat navs wouldn't work, but surely the bigger point should be, "How would you know, you're a basketball player!?"
Experts dedicate their lives to studying science and say the Earth is round, a famous person says it's flat and we bother to listen to him?
The same thing happens on the show, a researcher spends years looking at some data, finds a conclusion that gets in the news and someone will call in to say, "I've thought about that thing I've just heard about and I don't think they're right."
But you can't say the researchers are cleverer because we have to stroke the ego of the least smart. We pretend that no one is more intelligent than anyone else in case someone gets offended. Why? We don't pretend we're all the same height.
If Prof Stephen Hawkin called me stupid I'd have to take it. Fair point. I'd agree. And so would a lot of other people. But that's because he's famous.
