“Celebrities often make wildly inaccurate claims and comments to millions of people. But the workings of our minds mean we’re all prone to such behaviour.”
“Without being too harsh, the Dunning-Kruger effect must be considered. Achieving high profile or celebrity status in the modern world is no indication of intelligence, and the effect shows that “low intelligence” is often accompanied by increased confidence in ones opinions and an apparent inability to accurately judge your own abilities and expertise in comparison to others. A willingness to present your poorly-thought-out conclusions as cast iron facts would be an inevitable consequence of this.”
