The people who fuel bad ideas are often the very people trying to destroy them. Experts will argue against a bad idea until they are blue in the face and then get exasperated when people continue to believe them. But they fail to realize they spent 90 percent of their time discussing why a bad idea is false and only 10 percent explaining how a good idea is true. In other words, they gave the bulk of their time and attention to a bad idea.
What is someone more likely to remember? The thing you spent 90 percent of your time talking about? Or the thing you spent 10 percent of the time talking about? Experts wonder why people continue to believe bad ideas, but fail to realize that they are giving bad ideas far too much airtime.
Thus, we get to one of the key features of debunking wrong beliefs:
The best thing that can happen to a bad idea is that it is forgotten. The best thing that can happen to a good idea is that it is shared. Don’t waste time explaining why bad ideas are bad. Instead, explain why good ideas are good.
Spend your energy explaining why good ideas are right, not what bad ideas are wrong. Do not fan the flame of ignorance and stupidity. Spread intelligent ideas.
Thus, it is better to pour your energy into good ideas and let bad ideas fade away. —James Clear
Is there something to apply here to the preaching and teaching of the gospel?
I recall a teacher, in a course on denominational doctrines, saying that the best way to refute a false teaching was to put forth positively what the Bible teaches on the subject. I forgot much of what we studied in that course, but that principle has always stuck with me, even in moments when I didn’t practice it in the best way.
