Other way around. To quote the article:

> To conduct the literature review, the sugar industry paid the Harvard scientists the equivalent of $50,000 in 2016 dollars [...]

So it was actually about ~$5,000 in 1965 dollars.

… it's $68,404 in today's dollars, according to BLS's inflation calc.

(…your figure works out to a 26% per annum inflation rate. The $50k figure is in 2016 dollars — "the sugar industry paid the Harvard scientists the equivalent of $50,000 in 2016 dollars".)

The $50k is already adjusted for inflation.

Ah. My bad, then.

No, that's already inflation adjusted.
