Perhaps the three hardest words to say in the English language. But perhaps they are also words we should be using more often. You don’t have to look far back into history where people believed things that we would now see as ridiculous: a flat Earth, a sun that orbits us or that blood letting was an effective medical practice. Similarly I don’t think you need to look far back into your personal history to find examples of where you have been wrong. Relationships you felt would last forever that didn’t make three weeks. Career paths you ignored. Beliefs you held that turned out to be false. Benefits of Skeptical (and Critical) Thinking There are a lot of practical applications for using skeptical thinking. Unfortunately, with the recent popularity of programs like The Secret and positive thinking self-help, rational thinking is being subverted for a self-induced placebo effect. Here are some benefits you can get from using skepticism on practical matters:

Creativity – The best way to prevent new solutions is to believe you already have the answer. Allowing a gap of doubt can allow creative alternatives to flow in. If you are adamant that advertising will not work for your product, you might cut off hundreds of ideas for improving your business. Planning – Assumptions are the enemy of planning. A common rule of thumb for software development is to plan to use double the amount of time you need; then add six months. Write your plans too narrowly and they may collapse under new information. Quickly Integrate New Facts – When you also maintain a small margin of doubt, you can allow in new facts easily. If you are completely certain your approach is perfect, you won’t be able to adjust when evidence points that it isn’t. Reveal Weaknesses – Many of the things that sabotage your efforts will be completely unknown. Thinking critically and examining the information can reveal some of these traps.

Becoming a Better Skeptic Here are some ways you can integrate healthy skepticism into your life: Avoid Turning Skepticism into Cynicism Healthy skepticism, questioning your underlying assumptions and introducing doubt, can be helpful. Cynicism takes it further where doubt becomes mistrust and paranoia. Avoid that trap. Become an effective skeptic and be able to take the best information available and knowing what information you need to be proven wrong.
