Retired medical microbiologist. Previous interest in biological evolution now largely superseded by interest in the global interplay of language, intelligence and ideas.
Je suis désolé, je me suis trompé parce que DuckDuckGo m’a égaré.

That’s like the advice I gave a trainee 40 years ago. He asked how to get published. I said read the latest publications, spot the errors and write about them. I was delighted to find that he became a professor in record time.

There’s a system of perverse incentives flooding the field with waste. To paraphrase Upton Sinclair, learning that you cannot simply chuck all the variables you’ve coded from the medical charts into a regression model and create a story about the p-values will only hinder clinicians’ careers.

In a field where evidence suggests that a high proportion of papers have serious flaws, a database of "potentially important" papers which appear *not* to have serious flaws might be useful, as well as identifying those that do.

Step into the shower. That always makes a delivery arrive at that very moment.

This is how the universe works, it’s called Intelligent Design.

With the notable exception of Evri (which commonly postpones deliveries), most couriers give rural Anglesey a surprisingly good service. To the extent that on at least two occasions I have had a van parked outside waiting because it had arrived before the beginning of its scheduled two-hour slot.

Finally, a bit of a reality check from our 2024 election book (out soon!) for everyone hyperventilating about collapsing public trust in the BBC - free to air TV (mostly the BBC) is still the most widely consumed and widely trusted source of news - blows print, online & social media out of the water

Sorry, I should’ve said I am not American and I prefer the white one.

The one on the right gets my vote. It’s much more eye catching and the subject matter is more obvious, whereas the one on the left could be mistaken for a board game.
