“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.”
