Today's guest is The Economist Tim Harford.

0:09.0

Tim's a well-known media figure here in the UK.

0:13.0

He's a best-selling author, newspaper columnist, podcaster, you name it.

0:18.0

But for the longest time, he's been best known to me for his excellent BBC radio show,

0:23.1

more or less. And that's where our conversation started. What will people hear if they

0:30.7

stumble over an episode or more or less? It's going to be you talking to people about what?

0:34.7

Yeah, me talking to people about numbers. That's the, that's the thing, but particularly about statistics more often than pure maths, although we had features about

0:45.0

John Conway, for example, when he died. So we do talk about pure maths too. But your classic

0:51.1

episode of more or less, it's nearly half an hour long, and we'll go through

1:24.0

of the numbers or hang on, that's not exactly the way it seems and trying to set the record

1:27.9

straight the thing that we did a great deal of earlier this year was simply to examine the

1:33.4

British government's record on testing because the British government was making a lot of promises

1:37.7

about scaling up testing for SARS-CoF 2 the virus that causes, and they said a lot of things that seemed a bit

1:46.2

implausible, and they measured their data in pretty odd ways. And so we were just chasing them down

1:51.9

and holding them to account, how many tests are they actually carrying out? And how many people

1:57.7
