There doesn't seem to be anything unusual about the heights of the presidents and first ladies in the picture above, taken in 1991. Or is there? Laura Beck went down the internet rabbit hole and came back with a cautionary tale about the believability of internet sources. She recalled former first lady Barbara Bush as an "imposing figure," and then asked Siri how tall she is. Siri responded that Barbara Bush is four feet tall. What? Siri cited her source as Wikipedia, but the entry for Bush does not mention her height. Neither do many other resources that you would expect. That set off a flurry of research with no consensus.
Beck also looked into the possibility that Bush's height was misrepresented to us in photographs, with a few funny responses. The only other internet source that claimed to know said that Barbara Bush is six feet tall. One can assume the truth is somewhere between the two extremes, but the moral of the story is never take information at face value. Read the whole saga of Barbara Bush's height at Jezebel. -via Digg
