Strong opinions, weakly held

This a long but powerful quote:

The fastest way to an effective forecast is often through a sequence of lousy forecasts. Instead of withholding judgment until an exhaustive search for data is complete, I will force myself to make a tentative forecast based on the information available, and then systematically tear it apart, using the insights gained to guide my search for further indicators and information. Iterate the process a few times, and it is surprising how quickly one can get to a useful forecast.


Since the mid-1980s, my mantra for this process is “strong opinions, weakly held.” Allow your intuition to guide you to a conclusion, no matter how imperfect — this is the “strong opinion” part. Then –and this is the “weakly held” part– prove yourself wrong. Engage in creative doubt. Look for information that doesn’t fit, or indicators that pointing in an entirely different direction. Eventually your intuition will kick in and a new hypothesis will emerge out of the rubble, ready to be ruthlessly torn apart once again. You will be surprised by how quickly the sequence of faulty forecasts will deliver you to a useful result. - Paul Saffo, circa 2008

Weak opinions are problematic because people aren’t inspired to develop the best arguments possible for them, or to put forth the energy required to test them.

Equally, don’t be too attached to what you believe, otherwise, it undermines your ability to “see” and “hear” evidence that clashes with your opinions. This is what psychologists sometimes call the problem of ”Confirmation Bias."" (not included in the LYT Kit)
