- nonbel 8y agoIt's a fundamental problem with modern day medical research. Rational people would start from the principle that "every x is correlated somehow to every y" (in this case "every aspect of the human body and environment is related to aging"). Now that aspect is taken care of, so rational people can proceed to figuring out quantitative models of these relationships. However, the current paradigm is to reward people who check for "significant differences/correlations", which just means that they "discover" all these non-zero correlations. Basically it is a huge waste of time and money but it works really well to generate an endless series of breathless press releases.
- cycrutchfield 8y agoGo ahead and knock yourself out. If you think “creating a quantitative model” of senescence is easy for “rational people”, then go right ahead. Your Nobel prize awaits.
- nonbel 8y agoWell, I didn't study senescence but actually did do something similar. It required training myself in math, programming, history of the topic, and stats in addition to the normal grad school stuff (memorizing stuff for classes, data collection, etc) which amounted to about 3 years of working almost nonstop. Turns out nobody cared, all they wanted to know is if there was a significant difference between groups. My attempt caused me health, financial, and social problems for literally an anti-reward so I would not recommend anyone try it. I also don't believe anyone would get a nobel prize for that in the current environment, they would be ignored or fought against because some holy cows would need to be sacrificed. EDIT: As a more concrete example. Look at the pushback against Tomasetti & Vogelstein for daring to point out that there is a base rate of mutations per cell division and accumulated mutations lead to cancer, so cancers arise more often in tissues with more divisions. This is almost common sense, but people cannot handle it for some reason: https://www.theatlantic.com/science/archive/2017/03/no-cancer-isnt-mostly-bad-luck/521049/ https://www.theatlantic.com/science/archive/2017/03/no-cance...
- toopsss 8y agoYes there are some idiots that dismissed the tomasetti and vogelsteinn paper due to it conflicting with their worldview, but they only got momentum because the original paper really was crap from even a critical scientific POV. What’s very ironic is that the problems with the paper seem to be the same things you’re bitching about in your post. No one smart is criticizing the paper for the “common sense” part, but because they actually tried to quantify it and their method was quite flawed.
- nonbel 8y agoWhat were the problems in that paper? The good stuff is that they were able to come up with estimates for stem cell divisions and were able to see a correlation with the cancer risk. The bad stuff was the usual misinterpreting correlation coefficients and p-values (this is standard, found in pretty much every paper) and that the data is messy/incomplete. I mean, sure more people should be working on figuring out the number of stem cell divisions by tissue and other nations should collect data of the same quality as SEER... If it was just another standard "smoking/sunlight/etc causes cancer" paper with the same issues there would not have been this response. It even says so in the atlantic, people think this information undermines their public health campaigns: >'The paper triggered a hailstorm of criticism. Some scientists chastised the methods. Why did they ignore common cancers like breast and prostate? Why did they only focus on the U.S.? Others accused the duo of undermining public health. Many personal choices, from quitting smoking to staying lean, can dramatically reduce one’s risk of cancers, but why would you bother if you read headlines saying that these diseases are “largely down to bad luck?”' https://www.theatlantic.com/science/archive/2017/03/no-cancer-isnt-mostly-bad-luck/521049/ https://www.theatlantic.com/science/archive/2017/03/no-cance...
- i000 8y agoI would suggest you do not use your personal failures and frustrations as justification to call other researchers work a waste of time. Please go ahead and explain to us how their contribution to science is a waste of time and money (you could for example contrast it with your own accomplishments).
