Reddit reviews The Half-Life of Facts: Why Everything We Know Has an Expiration Date

Sometimes things that are apparently "scientific consensus" aren't at all, like that saturated fat is a significant contributor to heart disease. That started with some doctors recommending a low saturated fat diet to heart patients and it seemed to work. It became conventional wisdom and even a government recommendation, but there weren't scientific studies to back it up. Now that the studies have been done it appears that the conventional wisdom (not scientific consensus) was largely wrong.

So I think a lot of the stuff that has been changed just hadn't been scientifically studied in the first place. But that aside there is an idea called "the half life of facts" or "the half life of knowledge" that suggests that about half of our scientific knowedge today will be obsolete or proven wrong in about 45 years.

Somebody wrote a book about it which I hope to read sometime before the end of the year. "Half Life of Facts: Why everything we know has an expiration date"

I also like titles, doesn't mean that everything you read is true.

But let's say that Europeans and Russians did create Israel.
I doubt that happened considering that most Russians Jews were only allowed to leave in the late 1980's almost 40 years after the creation of Israel.

I don't know where these mythical Jews came from. And those Europeans were mostly holocaust survivors so I don't see the relationship?

You do know that there are more Sephardic jews than Ashkenazi jews right? As in more Sephardic jews at the creation of Israel.

So....

> A true fact, as opposed to a false fact.

People think things are facts and later find out they were incorrect.

The half life of facts in the social sciences is shorter than the half life of facts on the hard sciences. "Truths" are more frequently overturned, say every 5 years in psychology about 50% of accepted truths are proven wrong. In physics it's about every 15 years (or something) that 50% of the "truths" are proven wrong.

This is how science works, constantly revising itself. Different disciplines just have different rates.
