My problem is both with the statistic quoted by Puppet ( Ironic nickname
) and just about all these sorts of statistics, I've ranted about how wrong a lot of them are before and even the ones that show some consistency shouldn't necessarily be considered as examples or proof that laws or stereotypes about people or objects is true.
I'll give out a more local one for instance since you said your in Wales, I'm sure you know about the shitty situation we have when it comes to car insurance particularly with young drivers, car insurance companies claim that under 25 etc. are involved in accidents so they charge more because of the risk, but lets backup a few minutes. They've been saying it for years now, with how high they've been pricing and the prices they charge could only be done if they either caused a multi-car pileup on a motorway ( I'm not joking because I've seen prices of £22,000 a year ) or if they drove a tank into some buildings. Not only that they've decided that somehow even with decade old cars which are falling to pieces and more of a threat to the driver than anyone else are a threat with someone young at the wheel. Then there's the fact that more recently those statistics even if they were a 100% are going to be wrong now because the majority of young drivers will be forced off the road because of the stupidly high prices.
It's not a misunderstanding, statistics a lot of the time are a load of bullshit, it doesn't matter if they paint it pink and spray it with perfume or state it isn't bullshit, it still is, Puppet, I've always said I'm shit at math but per 100k is still meaningless to the millions that are left out and then you still have situations where the 100k in that group will all have varying situations, backgrounds and experiences, the problem is you're applying math to something that isn't logical, humanity doesn't follow mathematics, they just use it as a tool. Adding to that, you can't just group everyone together, we all do it at times but when you're actually trying to apply a law or rule to that will be enforced it's a shitty thing to do to people which is why they take it personally because it may not even apply to them.
There certainly are bullshit statistics but with your current lack of understanding I'm afraid you're not qualified to call them that other than if you're just repeating someone else. But again, if you're repeating without having properly understood the reason something may be bullshit then you're leaving yourself open to questioning or criticism that you're unable to defend. Getting more angry and calling people idiots from where you are in your understanding of statistics is not a good idea!
I am no statistician but if you want to be able to present your ideas convincingly or refute a statistics-supported claim without losing credibility I would first recommend you say nothing more about statistics and focus on the non-statistics element until you have done a little background reading and at least understood the very basics. For now just stay away from the numbers! Second I would recommend sometime in your future, ideally sooner rather than later, finding some videos or a book by a statistician who teaches well
and shares your world view (I would recommend Hans Rosling's Ted Talk videos other than that I think he would annoy you so much with his 'public policy' world views that you would lose patience and not learn anything!) It is not necessary to learn a huge amount before some numbers you're presented with begin to allow you to see the world quite differently leaving you more informed and better armed to make whichever argument you wish to. My guess is you'd find it enlightening.
Best, tf
