"Excuse me, but I am curious as to
the source of your misinformation."
Researchers in Australia did experiments where they showed an effect called a "continued influence effect of misinformation", where they found we cannot completely forget a false belief, even if we’re told our first belief was false, and even if we believe, understand and remember that our first belief was false.
A strong retraction does help to eliminate the belief, but, said Assistant Professor Ullrich Ecker:
"Despite best efforts to correct misinformation it can’t be completely eliminated."
They did find two ways to partially reduce the influence of false information.
One is to make people suspicious of why they were told the information in the first place. If people are told that the initial information was trying to mislead them, they’re more likely to dismiss it.
Another way is to make people conscious of this "influence effect" by telling them that the corrected misinformation will continue to influence them, which lessens the influence of the information.
