In trading, we can all agree that fewer conditions or filters results in better conclusions, better understanding, and less curve fitting. Conditions or filters block information. Too filters can result in less new insight and fewer opportunities.

Here is where trading is a good lesson for life. As we grow older our tendency is to filter out information, people, paths. It’s partly a necessity to avoid the bad or overload, but good things can be missed. Our experience tends to specialize our knowledge and narrow our focus. Though this has some benefit in expertise what opportunities or knowledge or growth may be missed. Ignoring, filtering or refusing to hear or listen to ideas we disagree with or that are different than our own may lead to narrow mindedness, missed opportunity to change and important information. For younger people it might be seen as closing doors. Meeting new people, hearing new ideas, going to new places. Nobel laureates advise not to tighten parameters too tightly as the surprise result may reveal itself. I recommend opening up parameters, let the fresh air in. Let’s not become grumpy old men. We’ve seen closed small minded people and don’t look on them with respect. Broad vision is necessary to see above and beyond the noise. You really need to force yourself against the tendency to close the mind.
