Great question @JonnyPitt.
Good points @Srinath, I was literally writing something equivalent. I think people tend not to understand the concepts of hypotheses, models, the probabilistic nature of things and find the constant changing of boundaries and facts perplexing and overwhelming and incredulous like being grounded on shifting sands.
Specialisation has definitely become a bigger problem and the lag in independent verification of scientific papers, as evidenced say with big pharma over simplified models on depression or the false promises of Theranos the company that promised breakthrough blood tests and were able to reach a $10billion valuation without definitive evidence of their products claims.
What is interesting to see is that there are different standards and methods used across the different disciplines in science as well, for example in my background in physics a lot was pushed to the whole 5 sigma criteria, which is 5 standard deviations of a Gaussian mean, which means a probability of being incorrect would be 0.000027%.
Some systems are so complex, dynamic and constitute so many different variables and parameters that there is a slim chance to ever probably be able to reach a 5 sigma criterion, and in some cases it will not be relevant because not everything fits a Gaussian model either.
A doctor determining somebody’s diagnosis based on blood results, histologies and imaging isn’t going to adhere to some 5 sigma standard before attempting to diagnose and treat their patient.
Again, the emphasis of the scientific method is reproducibility and prediction and in some systems the accuracy of our predictions aren’t great but that doesn’t mean they are irrelevant or negligible.
Take the smoking situation, I think the problem comes down to the probabilistic nature of dynamic systems. People are often looking for a simple case of a mono-cause and effect, but in dynamics systems with varying attributes it is hard to demonstrate a mono-cause. When you have complex factors like heriditary/genetic influences, environment influences (living near a polluted city for example) and then habitual individualistic differences. The subtle individual differences can be really complicated as well, maybe somebody smokes their own rolled up tobacco which then has less additional chemicals in it as standard cigarettes, maybe somebody inhales and holds the smoke in longer, maybe somebody also smokes weed occasionally, etc, it is very hard to measure all of these subtle differences.
That is why a lot of tests sought to use twins to gauge a deeper understanding of the increased probability of getting lung cancer from smoking when the genetic and environment influences are the same but only the individualistic choices are different.
However, because there is not a singular causal link showing that smoking causes lung cancer it doesn’t mean that there isn’t a higher probability of getting it from taking that activity.
Also, interesting how we pick and choose what is relevant to us.
The same type of epidemiogical studies were used to determine that Chromium VI (the whole Erin Brockovich film is about this poisoning) is carcinogenic and can cause lung cancer.
If Richard and Vineeto were to find their water supply contaminated with it, would they be as nonchalant about it being in their water supply and being a possible risk factor for lung cancer. Or would they say, its fine there is no definitive causal link.
I personally don’t care whether somebody smokes or not, most of my family do, my dad did despite COPD and prostate cancer with lung mets, it is a personal choice and as long as its not blown in my face all the time I don’t care. But it is interesting to see where people decide to accept and reject certain information.
I have learned to accept the limitations of my understanding and awareness. However, even when I don’t fully understand something, I find I am still able to ask questions that help me understand or challenge the validity of something. I guess I am always looking for holes in something, seeing and testing in my mind if I can find problems and seek greater understanding. I find sometimes a good question can show up a flaw in ones argument or reasoning just as much (sometimes more) than a counter argument.
I had a chance to message Richard back in the Topica and Yahoo days but performance anxiety blocked me in that regard. Though I used to have questions I would want to ask. Previously on the other forum I questioned Craig a lot regarding the beliefs he seemed to still have which didn’t sit right with me and I was never answered, not that I have to be but I thought I raised fair and valid questions in a respectful manner. All that is lost anyway…thanks srid.
As regards climate change, it is true that there is no supercomputer yet capable of accurately modelling everything and making an absolutely accurate prediction. The absolute worse case scenario of human extinction might not be a valid conclusion however there is now evidence that human activity has contributed to changes in the atmosphere, ocean, cryosphere and biosphere (to quote NASA lol). So, again we can’t say we have a non existent negiblible impact on our environment.
I guess any time I consider anything that threatens the validity of what actual freedom is about I get this uncomfortable defensive reaction. This happened with things raised in this forum such as actualism and the weird thread. Additionally, the expectations I have of what could tarnish the value of being free, it is because I had some ideal that it wouldn’t allow things I feel bad about such as bias, stupidity, clumsiness, errors/mistakes and other such problems that actual freedom won’t rule out still being a possibility. I.e. it is not some idealised intellectual state that I wish for, like my wish for photographic memory.
I have read a lot of examples that seem to indicate exposure to people who disagree with us or have different perspectives and biases to us, is always good for shining awareness on our own biases. Maybe the reality is some people aren’t exposed to varying opinions. I always thought it was a benefit of living in places like London with such a complex melting point of different people, different beliefs, philosophies, races, upbringings, class etc. Harder for someone in a mono culture where the majority of the community look and believe the same thing to challenege biases, or other things like beliefs, cultural norms etc.
