How much of what we 'know' is actually wrong?


Recommended Posts

Just a curious little thought I've been having over the last few days... when we look back at science or medicine, it's pretty easy to actually laugh at some of the theories and treatments that were accepted in the past. In their time, some of 'em even seemingly had evidence on their side. Why should what we 'know' today be any different? Has anyone else ever thought about how many of our scientific theories, for instance, are totally wrong? And what about medical treatments - some of the thing we're doing today are probably just as stupid as bloodletting.

Science is just best guess with what we know today, the science of tomorrow will always be different. What we know now isn't necessarily wrong maybemore like inefficient. When it comes to quantum mechanics and stuff were still just in nursery school at best

I'm absolutely sure of this, it's clear that a lot of what we do is more harmful than helpful.

It's getting borderline ridiculous how much medical advice there is out there, you can never be sure it's accurate or right. Everyone's saying different. An newspaper article might say drinking a glass of wine a day will reduce heart disease, another article saying eating carrots or some other will reduce the chance of a type of cancer. And all the weight loss methods seem to be a sham.

I think it's getting worse :/

That's exactly what science is all about - that nothing is 100% true, ever. Those small control groups and a few years of testing (especially on non-humans) cannot account for all the genetic diversity of humans. And then there's too many charlatans, idiots and those looking to profit from it.

its called evolution. The evolution of the information. Of course most of the nowaday theories/technology are damn wrong, but we live on this time and we handle them the best we can.

EVOLUTION IS A LIE! GOD CREATED KNOWLEDGE! :rolleyes:

Just remember that once it was a "fact" that the Earth was flat and the sun revolved around it. It's wasn't an opinion or theory, it was a 100% given fact.

Yeah, that's exactly what I'm saying. I'm not just talking about theories or even medical treatments - it's just kind of humbling to think that some of what we consider to be 'fact' today is probably bogus.

the difference between knowledge today and knowledge a thousand years ago is the methodology we use to obtain said knowledge, so given the significantly increased rigour it's reasonable to expect that a much smaller portion of today's knowledge is blatantly false, than it used to be. But we can't tell, of course, which of our investigative limits is actually giving us a wrong impression simply by asking this question within the same limits, it'd take an expansion of our powers of investigation to figure that out.
