How you spend your time (and attention) as a trader is a key driver in your eventual performance. We all have a limited amount of time we can devote to the markets, therefore maximizing the impact of that time is crucial. This point was driven home in reading Margaret Heffernan’s interesting newish book Willful Blindness: Why We Ignore the Obvious at Our Peril in which she writes:
After a decade of experiments by himself and others [Dr. Daniel] Simons, concludes that we see what we expect to see and are blind to the unexpected. And there are absolute hard limits to how much we can take in at any given time.
“For the human brain,” say Simons, “attention is a zero-sum game: If we pay more attention to one place, object or event, we necessarily pay less attention to others.”
Our attention is a limited resource worth shepherding. The question is for traders whether their time is well-spent watching financial television? The problem is that the way television is designed disrupts our ability to think. Heffernan writes:
The bottleneck that characterizes our ability to receive information explains why we cannot intelligently absorb all the information presented to us on TV screens like those displayed by CNN, Fox and CNBC. The scrolling text, sidebars and stock prices don’t make us smarter or better informed; they make us stupid. While we are watching such a busy array, we can’t efficiently think, discriminate or make critical judgments.
Trading is hard enough under the best of circumstances. If you continuously expose yourself to inputs that don’t make you “smarter or better informed” you are doing yourself a disservice.
