Recently, we at Daruma got our inner spook on – we attended a two-day seminar held by ex-CIA types. The purpose of the class was to help us get better at gauging "truthiness" in our interactions with the outside world, without resorting to advanced techniques such as waterboarding.

While I can't tell you the precise details of our training (I'd have to kill you), I can share some of the valuable reminders that the training brought home to me about selective attention and mental filters and, in particular, why these matter in investing.

To kick off the session, we played "find the liar" in a group of people. There was wide disagreement among us. Two days later, at the end of the session, we took the test again. This time, we were all on exactly the same page regarding who was the Pinocchio in the bunch.

But why? How could we see the exact same thing twice yet come to a radically different conclusion the second time around?

The answer, in large part, has to do with filtering. The world is a sensorily rich place – our heads would explode if we tried to process everything our senses take in. In order to cope, our brains decide (sometimes at our behest, sometimes not) what to pay attention to and what to ignore. We tend to notice what has meaning to us and ignore everything else, a predisposition that leads to attentional blindness.

A walk in the woods with a lumberjack, for example, is going to give you a different perspective on trees than that same walk would with an arborist. Or a mushroom forager. Or a bird watcher. It's the exact same walk but you will "see" a different forest because the brain of each expert filters things differently.

Back to our friends the spooks. Once they taught us what to look for, our attention was focused on the things that mattered relative to truth-telling. (Hint: It's not the body language clichés you learned in Psych 101.) The second time we took the test we gleaned signals that had before seemed random (and had therefore gone unnoticed).

So it goes with investing – you find what you are looking for.
