Many
of us have been wondering how people can continue to believe the fake news that
is flowing freely out there these days even when presented with facts to the
contrary.
We've
already discussed the primacy theory, which says that people tend to believe
the first thing that they hear. And selective
perception which allows them to filter out conflicting information in order to
avoid cognitive dissonance. That's the
uncomfortable feeling that you get when something contradicts what you believe
to be true. Here's a blog about those
concepts...
Then
there is the disturbing finding that if we hear a lie often enough we think it
is true. This happens because we mistake
familiarity for truth. That's when you
say - "I think I've heard that before..." Here's a blog about that...
But
there's another piece of the puzzle that we haven't discussed yet. And that's the role that involvement, or lack
thereof plays in the equation.
Research
tells us that when people are involved in an issue then they are responsive to
strong central arguments. But when they
are not involved they tend to rely on credibility and context.
Think
about that a moment. After multiple
years of hearing that reliable news sources are in fact sharing fake news, a
lie they now believe, people no longer listen to the facts no matter how well
supported they are, but instead discount them based on the perceived lack of
credibility of the source. (Haugtvedt, Petty, Cacioppo, 1992)
This
takes us back to the finding that all decisions are emotional. And makes a strong case for abandoning facts
altogether when trying to persuade someone to change their mind.
