The study below puts the figure at 8%. Not a big ratio, but it equates to a substantial number of people.
Public Opinion on Religion and Science in the United States
That study says 2% of scientists believe in creationism.
And they only look at America (creationist hotbed), while polling a subset of scientists in the AAAS, which states they’re aiming to influence politics.
If the most favourable conditions possible for producing a creationist scientist only creates 2% of them, then what would be the real figure throughout the world?
No scientistic who understands the scientific method and has honestly attempted to learn even the basics of evolution can be a creationist. It’s directly contradictory to everything a scientist does.
Political agendas might influence the odd scientist to say otherwise.
If your basis for rejecting climate change is data from a creationist scientist covering a 2-5 generation timescale... I’d expect there’s significantly better data out there.
I don’t know anything on the topic though, so I’m just learning the basics from what I’m seeing by you guys on here and haven’t seen any data myself.
