If you’re familiar with US history or politics, you’ve likely heard plenty of debates about the best and worst presidents. But what about the smartest? Is it possible to objectively measure the intellectual horsepower of America’s past leaders and compare them to each other? Well, that’s exactly what we’re going to attempt in this video – by ranking US presidents according to their IQ.
Now, before we dive in, it’s worth acknowledging that IQ is just one measure of intelligence, and it’s not without controversy or limitations. It’s also important to note that the historical record isn’t always clear on the exact IQ scores of every president – so, we’ll be relying on estimates and anecdotal evidence in some cases.
So, what’s the range of presidential IQs? As it turns out, there’s a pretty significant gap between the highest and lowest scores. On the high end, we have some of the most renowned intellectuals in American history – men who were accomplished scholars, inventors, and polymaths. On the low end, we have presidents who were widely regarded as mediocre or worse, both in terms of their intellect and their overall performance in office.
While we’d love to cover all of the US Presidents in this video, we only have enough time to count down the top 10 US presidents.With that in mind, get ready for a little trip back through history as Facts Verse Presents: US Presidents Ranked by IQ and it’s Not Even Close
