Alas poor humanity! We love jumping to conclusions. We pin the blame on pet hobby horses and remain convinced of their guilt even if they're later proved to be completely innocent. We think savage punishments are the answer to crimes that never happened. We enjoy newspapers like the the Daily Fail because they whip up our sense of righteousness indignation, even when the journalists know the story is bollocks.
My theory is that evolution is to blame. If you catch a movement out of the corner of your eye, instinct says 'react – it's a bear'. That the fact of meeting a bear in your kitchen is unlikely makes no difference. For a brief moment logic disappears, and 'fight' or 'flight' become the only options on the table. We behave like startled birds. If one reacts to a perceived threat the whole flock panics, leaping into the air and squawking alarm calls to make sure the entire flock escapes. Makes good sense if you're a starling and there's a cat about, not so clever if you're a member of a technological society at an airport.
Our brains are wired for pattern recognition. Much of what detect is real, quite a lot is wrong. We see castles in the fire. We blame foreigners for all our ills despite evidence to the contrary. Ghosts, the Loch Ness Monster, UFOs, dreams, and extremism are probably all due to signals being decoded wrongly.
Curious thing is, once one person reports seeing something, other people will see it too. Or at least they think they've seen it! People convinced only they know the truth make politics and religion dangerous subjects to debate.
It's not that feelings and beliefs don't matter, but engineers should surely be wide awake to the possibility that perceptions are not facts. I'd define an engineer firstly as a man(or woman) who makes things work, and secondly as a man who makes things work for minimum cost. Results are mainly achieved by a fact based approach. Solid facts are far more valuable than gut feel and snap judgements made in the absence of evidence.
Shooting from the hip is only OK in a gunfight – it's usually better to achieve results by thinking methods. I think engineers should moderate opinion by applying their analytical skills to to situations like this. Sadly, when the rest of the world has a dose of the screaming abdabs, engineers and rational thinkers become very unpopular. People don't like being told that they are being stupid, and most of us would rather carry on regardless than admit a mistake! The effect is particularly strong when a large group catches the same bug and when the mistake is enormous. I could mention Tulipomania, the South Sea Bubble, Stalinism, Fascism, Eugenics, Social Darwinism, and bombing Pearl Harbour!
New Years' resolution: Slow Down, Check Evidence, Engage Brain, Reject Emotional Inputs, and only then Decide. Even then, follow the evidence and be ready to change your mind as necessary to accommodate the facts. Mistakes are learning opportunities, there's no value in supporting incorrect beliefs.
