I know that I have posted before about Biden having a double. I pointed out that the Biden of today had different earlobes than the Biden of the past, and many of you blew it off, saying that it was because he had had a facelift. So let’s look at another subtle hint.
Here is Biden during last night’s address:

Now look at the Biden that was sworn in as President in 2021:

Here is Biden from June of 2021:

In each of these photos, compare the length of the index and ring fingers. The relationship between them, called the 2D:4D digit ratio, is determined by the testosterone and estrogen levels that are present during puberty. Some studies even show that the ratio is tied to performance on standardized tests like IQ tests and SAT tests.
In any case, it looks like the 2D:4D ratio on Biden’s hand is not constant. Even though there are not a lot of pictures of Biden’s hand that clearly show his fingers, the ratio does appear to vary somewhat when you look at some of them as opposed to others.
