- Peer pressure. We tend to be swayed by other people’s opinions if they are widely held. BBC journalist Fiona Bruce wrote and presented a documentary on Leonardo da Vinci this week. Of course, she went to the Louvre to look at the Mona Lisa close up. Although she confided to the camera that she was underwhelmed by the painting – in her opinion it was small, and dark, and uninspiring, millions of people flock (correction – used to flock) to the museum every year to see the painting which general opinion holds to be the most famous painting in the world.
- Opinion presentation. Opinions have a better chance of becoming widely accepted when they are set in an anecdotal background. We have all seen Facebook coronavirus ‘cures’ like drinking very hot water and gargling with salt which are always prefaced by an anecdote – ‘My wife’s sister’s Pilates teacher is married to a consultant ICU doctor at St Thomas’s who says that……’
- However barmy the idea, say it often enough and it begins to take hold. 5G telephone masts being responsible for coronavirus is a case in point.
- The Power of the Gun. Just as in the Old Wild West; where law and order breaks down the opinion of the most powerful takes over. When you don’t know what to believe because the data is all over the place you are most likely to believe who you think is the most authoritative source. The BBC? Or Fox News? Or Russian TV? Matt Hancock? Or Jonathan Ashcroft? Or Munira Wilson? Or David Icke?
- Cognitive Dissonance. We want to believe that in this crisis the Government are doing a good job (our lives depend on it). So we are prepared to believe the data they give us about the millions of items of PPE that they say have been sourced and shipped, and their herculean efforts to get more. We want to believe the front line doctors and nurses (our lives depend on them) who provide data on the chronic shortages of PPE they are actually experiencing. We fail to rationalise the chasm between the two sets of data. So we are left to form an opinion about which set of data is more right, and we do so on the basis of which causes us less feeling of discomfort (dissonance).
