The New Consensus Study

on evolution:

Our search resulted in 487,629 papers that mentioned “evolution” or “natural selection” in the abstract. However 451,412 of those could not definitively be placed into one of our seven position-defining categories*, no matter how hard we tried with our group of 20 reviewers. [The consensus view among us is that these reviewers are completely independent and objective; their common participation at our web site devoted to presenting pro-selection arguments, but nothing to the contrary, is just not relevant in this case.**]

Of the remaining 36,217 papers, 35,167 (97.1%) supported the consensus position that over half of the observed evolution over the twentieth century is due to natural selection. The fact that only 126 of these 35,167 papers were actually focused on critically evaluating the topic at hand, i.e. the different possible mechanistic explanations of observed evolutionary change and/or speciation (e.g. random drift, founder and other stochastic events, mutation rate variation, instantaneous genetic barriers, etc), is an irrelevant point, a complete red herring. We can reasonably assume that in at least the majority of 50% of the time, none of these 35,167 authors would indicate agreement with a position that they themselves had not carefully investigated, without having more than half of a predominantly pretty good reason for so doing***. It’s just not really half as difficult as people make it out to be when you boil it down. As we have now done. For you.

In conclusion, there is very clearly a very strong consensus as to the influence of natural selection on evolution during the twentieth century and this consensus has been increasing as the evidence increases. It is important that policy makers realize this and take action. Please pick this up and disseminate it widely so everybody knows about it; everyone else is, so you will be part of the consensus effort if you do. Thank you.

Heh.

Financial Planning For Life Extension

An interview with Joel Garreau. Not sure I agree with this:

Boomer octogenarians in 2030 have “too many hard miles on their chassis” to fully benefit, but younger people may have trouble imagining the onetime prevalence of sickness and death.

I won’t be quite that old, but I think that there’s a good possibility that even for octo/nonoganerians there will be potential reversal of damage, and rejuvenation by then. And current government policies based on Scenario 1 (i.e., pretty much business as usual) are doomed to bankruptcy.

Peter Thiel And Global Warming

Why he’s skeptical:

“Whenever you can’t have a debate, I often think that’s evidence that there’s a problem,” Thiel said on The Glenn Beck Program. “When people use the word ‘science,’ it’s often a tell, like in poker, that you’re bluffing. It’s like we have ‘social science’ and we have ‘political science,’ [but] we don’t call it ‘physical science’ or ‘chemical science.’ We just call them physics and chemistry because we know they’re right.”

Thiel said no one will be upset if you ask questions about the periodic table, because it is actually science. But referring to man-made climate change as “science” tells you “that people are exaggerating and they’re bluffing a little bit,” Thiel said.

“The weather has not been getting warmer for the last 15 years. The hockey stick that Al Gore predicted in the early 2000s on the climate has not happened,” he remarked. “And I think as this monolithic culture breaks down, you can have more debates.”

Yes.

A Medical Breakthrough

An informational one:

…new recommendations regarding dietary fat from “what’s new Family Medicine” section.

Fat intake and coronary risk (April 2014)

Although it is known that there is a continuous graded relationship between serum cholesterol concentration and coronary heart disease (CHD), and that dietary intake of saturated fat raises total serum cholesterol, a 2014 meta-analysis of prospective observational studies found no association between intake of saturated fat and risk for CHD [7]. The meta-analysis also found no relationship between monounsaturated fat intake and CHD, but suggested a reduction in CHD with higher intake of omega-3 polyunsaturated fats; a benefit with omega-6 polyunsaturated fats remains uncertain. Given these results, we no longer suggest avoiding saturated fats per se, although many foods high in saturated fats are less healthy than foods containing lower levels. In particular, we no longer feel there is substantial evidence for choosing dairy products based on low fat content (such as choosing skim milk in preference to higher fat milk). We continue to advise reducing intake of trans fatty acids. (See “Dietary fat”, section on ‘Saturated fatty acids’.)

Better late than never.
