Everybody knows that bats are blind. It’s just one of those facts which is common knowledge, like the fact the only man-made object you can see from space is the Great Wall of China.
Facts like these have fallen so far into common parlance that, even with Google now at our fingertips, we often barely bother to check whether they are true or not.
This can be a bit like the investment funds we choose to put into our portfolios. When offered an opportunity to invest in an “amazing” new venture with high, uncorrelated returns, people want to believe.

When it comes to investing, you need to always listen to the voice of the whiney kid. We all know that he’s grown up to be a NASA scientist or similar because he made good choices and listened to his own voice of reason.
If you spoke to him now, he’d probably tell you not to go for that “amazing investment opportunity investing in a teak plantation in Guinea” but to take the more sensible option. Being a scientist, he could probably also tell you that all bats can in fact see and many have fantastic night vision.
He could also tell you that the Great Wall of China is actually barely visible from space but that you can see the Greenhouses of Almería, the Palace of the Parliament, Romania, the Kennecott Copper Mine, a lot of roads, cities and night pollution…
