In the 2016 movie Arrival, a linguist named Louise Banks is recruited by the military to learn an alien language that even the brightest minds on earth are unable to interpret. The story mixes ominous sci-fi themes with a personal arc interwoven in cut scenes that seem incongruous at times, but that ultimately reveal something surprising about the nature of reality. Without giving away too much, Louise eventually learns that language wires our brains in a way that shapes our perception of time. And when one learns to speak and think in a new way, standard ideas we all take for granted like the linear nature of past, present, and future no longer seem so set in stone.
While it makes for a cool movie, viewers may be surprised to learn that the core concept is based on actual psychological phenomenon. The way we speak, write, and think affects how we interpret the world around us. From the implicit framing bias we subtly insert into discussions by the words we choose to the linear performance charts that flow from left to right like our natural western language, words not only have meaning. They influence the way we think.
When discussing investing and the nuances of backtesting methodologies, I have come to learn that some of the concepts are hard to explain to everyone. It’s not that it’s rocket science. I think sometimes it’s just a new language that not everyone understands, and the thought process it nurtures takes time to sink in. Like moving from a sentence written from left to right to truly understanding the timeless circular ink blots on the window, it’s more than just about knowledge. It’s about how our minds work.
So if you’re interested in getting a glimpse through the glass to a different way to perceive investing numbers, grab some popcorn and find a comfortable chair. This article is for you.
