Valid Opinions and Objective Truth


A while back a friend made the woo-woo suggestion that all opinions are equally valid and equally true.

Imagine a group of Palaeolithic hunter-gatherers stalking a deer in a wood. The deer spooks and darts off. One of the hunters says it was a Spotted Pearlsbok, that always goes to ground a short distance away, and that the group should make loud noises to flush it out. Another hunter says it was a Spotted Milksbok, that always runs off completely, and that the group should look for new prey. It really matters to the group which of the two closely related species they have been stalking, but they are difficult to distinguish at a distance.

Here is the first point. Both hunters have expressed valid opinions. They are based on careful observation and objective experience. But notice an important thing about these two valid opinions – one is wrong, in the obvious sense of incorrectly describing the world in a significant way. This is a major pitfall for the irrational. They equate validity with truth, and end up having to say that valid, but mutually contradictory, claims are in some sense both true for the claimants. This is quite ridiculous. We might not know the identity, but the deer was either a Spotted Pearlsbok or a Spotted Milksbok. There is an objective reality. Both opinions are valid, but one is true and the other false, and the survival of the hunters may depend on which. Ignorance of the identity does not make both opinions true.

A third hunter cast sticks before the hunt and claims foreknowledge that the first animal would be a Striped Inksbok. He says that the spooked deer must be that. Here is the second point. This new claim is not valid in the same sense as the first two even though it purports to identify the deer. It isn’t valid in any meaningful way. It is not based on relevant observation, knowledge of deer, or anything rational of any kind. In fact, it is contrary to the evidence – two of the hunters saw spots, not stripes. Not all claims are equally valid.

This is the status of many religious claims. They often say no more than, “I have been vouchsafed a deep inner conviction that …”. Sometimes the believer will offer evidence as tenuous and irrelevant as the hunter’s sticks. Eg It must be true because it says so in my tribe’s holy book. Sometimes the claim is contrary to what we already know about the world. Eg A wafer and the body of a dead person can temporarily have the same essential reality. Or, the planet is no more than ten thousand years old.

One year a teenager joins the older hunters for his first hunt. He rather precociously proffers opinions on deer identity, and over the season he turns out to be very good at distinguishing. In fact, he always gets it right. He begins to imagine he has a special power and starts to claim communion with the spirit of the wood, and others believe him. Now, he does have a special power – he has superior eyesight, but you can see how the group might come to accept false explanations. Palaeolithic people were probably weak at critical thinking and the scientific method. If the hunter really was in touch with the spirit of the wood, then he would likely be able to identify deer without seeing them. So, there’s a simple test that might verify the idea. This is just an example to show how shamanic traditions might get started, with the associated claims having little basis in reality. No doubt many religions have begun like this.

Here are the go-away messages.

  • Not all claims are equally valid.
  • Not all valid claims are true.
  • Be very suspicious of claims offered without independent objective evidence.

Covering Your Router In Aluminium Foil

A friend was given a suggestion by someone from IT to alleviate network connection issues. The suggestion is to wrap their router in "tin foil". When they'd finished laughing, they called me for an opinion. Assuming they meant ordinary aluminium kitchen foil, the suggestion is ludicrous. The best you might hope for is that it doesn't make any difference. If it has any affect it would surely be to act as a Faraday cage, keeping external radiation out and internal radiation in. I decided to test it. I performed six throughput runs alternating between uncovered and loosely covered with a folded sheet of kitchen foil. Each run consisted of three one-minute trials, where TCP upstream and downstream speeds were averaged using TamoSoft Throughput. The server was my development PC upstairs; the client a downstairs laptop two metres from the router. Both were connected on the 5GHz WiFi band. Here are the results. The best you can say for the foil is tha...

BBC Cowering Before Right-Wing Authoritarianism

Gary Lineker is of course right in everything he says about the government's asylum policy. There are two issues. First, should a regular presenter be restricted from political comment outside the confines of their role, in the interests of public broadcast impartiality? The answer is obvious, and you would have thought that the BBC had learnt its lesson when it ended up apologizing for censuring Naga Munchetty for heartfelt comments on Donald Trump's blatant racism, following a public and internal outcry over her treatment. Munchetty's comments were made on a live BBC broadcast. Lineker's comments were off-air on his private social media account. Nobody is in any doubt that the comments are Lineker's rather than the BBC's. Second, how circumspect should anyone be about comparing right wing nationalism with the political ideology of the Nazis? The answer is very. But Lineker has indeed been cautious in his language. I pointed out myself in the lead-up to the...

Boris Johnson is a Pathological Liar

When I was a teenager, our class were caught gambling and the head decided to cane us. He lined us up to ask each child if they were involved. Nobody lied; the idea of dishonesty was much worse than the fear of corporal punishment. Boris Johnson is the exact opposite: a pathological liar; a delinquent who derives psychological satisfaction from the slightest deceit; from getting one over on people. And he covers up any exposed mendacity with further fabrications. He was unanimously found guilty of lying to the Head of State by eleven Supreme Court judges. He was fired from his job as a journalist for a campaign of systematic lies about the EU over a prolonged period and after multiple warnings. He conspired to deceive the nation before the Brexit vote with deliberately misleading financial propaganda, when the Treasury's own forecast for leaving was for significant long-term financial disadvantage. He knowingly lied about the difficulty of getting a Brexit settlement with the EU. W...
