Genuinely interesting, but I take it with a good dose of default skepticism.

Erst are you sceptical about? This is just a visualization of established scientific knowledge.

Data and methods, please. Why are you not skeptical?

Easy to miss on mobile. And I assume you’ve read this and examined the primary data? And you understand the methods? Because science is not trivial.

I’ve seen the same kind of visualization made from different sources before showing the same point. There is really nothing shocking or unbelievable in the picture?

It’s fine to be sceptical because it is an estimate. However it is a qualified estimate. Read more from the source: prb.org/…/how-many-people-have-ever-lived-on-eart…

If you have a better way of estimating the figure, I’m sure they would be all ears.

I do remember reading school books and science articles 30-40 years ago and the estimates then were different, but that’s just how science works.

Again it’s fine to be sceptical, but unless you can provide an alternative figure with better documentation, I really don’t understand why you’re encouraging people to be sceptical.

It’s almost as if you seem to have different motive, so I have decided to doubt your scepticism.

Because I’m a scientist and I know from being in the field that a lot of studies are wrong.

Source? 🤔
