  1. In Jordan B. Peterson's 12 Rules for Life: An Antidote to Chaos, he expresses support for the use of corporal punishment and argues that it can be an effective form of discipline.

  2. Oh, by the way, I forgot to mention this study by Fontana, Meyer, Klein, and Holloszy (2007). Even endurance athletes running an average of 48 miles a week for 21 years could not compete with sedentary vegans doing less than an hour of exercise a week, with regards to arterial health. References L. Fontana, T. E. Meyer, S. Klein, J. O. Holloszy. Long-term low-calorie low-protein vegan diet and endurance exercise are associated with low cardiometabolic risk.

  3. You're confusing anecdotes with empirical evidence. They're not the same thing. I have no idea why a community that ostensibly values empirical evidence is upvoting this comment. Evidence suggests Paleo diets negate benefits of exercise The problem with the Paleo diet argument
  4. In a recent video, Stef was speaking to a listener about pollution and brought up the issue of sedentary living and its negative effects. First, let me be clear, I am not disputing the negative effects of remaining sedentary for long periods, or the importance of exercise. But Stef, like many others, is vastly inflating the importance of exercise relative to other factors, namely diet. It's a common misconception (70% of people believe) that exercise and diet are both equally important to weight management and weight loss (International Food Information Council Foundation, 2011). This is simply untrue (Flatt, 2011). To quote Dr. Greger: 'What we put in our mouths is most important'. Regarding cancer, literally 5000 hours in the gym can't compete with a plant-based diet. Barnard et al. (2003) compared a group of participants eating a plant-based diet who did moderate exercise (i.e. walking) to another group who did daily, strenuous, hour-long exercise and ate a standard American diet, with a control group. After 14 years, the exercise group were still overweight whereas the diet and exercise group were a healthy weight. More importantly, the participants in the diet and exercise group were roughly twice as effective at fighting cancer growth compared to the exercise group. Another study by Jenkins et al. (2012) showed that consuming a cup a day of beans, chickpeas, or lentils for three months may reduce one's resting heart rate by as much as 250 hours on a treadmill. I strongly urge FDR to shine a light on the importance of diet. I have already posted about nutrition, twice. My first post didn't get much traction but my more recent post seems to have been well-received. References Barnard RJ, Ngo TH, Leung PS, Aronson WJ, Golding LA. Prostate.

  5. Hi AccuTron, it's great to see that you're looking to make some positive dietary changes in your life. However, before you change anything, I would recommend getting a blood test. The reason for this, is that in the future after you've changed your diet, if you get a health check-up and find out you're deficient in a particular nutrient, it may be difficult to know the cause of that deficiency. Someone who doesn't take this precaution may assume his/her change in diet was the cause of a deficiency that they already had, before the change. That's why I think it's good to know what your baseline is before making any changes. As for protein, well, to people who eat a plant-based diet, asking about where to get your protein is akin to asking an anarcho-capitalist "who will build the roads?". Protein is nothing to worry about. In fact, most Americans are far more in need of fiber than protein. Here's Dr. Greger to put you at ease: p.s. I'm happy to answer more of your questions if you have any. I've been eating a plant-based diet for about 7 years.
  6. Essential viewing Description: In this “best-of” compilation of his last four year-in-review presentations, Dr. Greger explains what we can do about the #1 cause of death and disability: our diet.

  7. Hello Everyone, I made a short presentation (7 min) on corporal punishment. It's unlisted on YouTube, at the moment. The idea was to create a sort of 'pilot' for a YouTube channel called 'PsychologyTube', that I'm thinking about starting in the future. The idea for the channel was somewhat inspired by an existing channel called 'Philosophy Tube'. The presentation style and concept were more appealing to me than the actual content - the presenter is pretty Left-leaning. Anyway, I'd really appreciate some feedback. I think the quality is OK, considering it was created with a smart phone. If, in the future, I can prove to myself and the viewers that I'm capable of making good content, consistently, I will invest in superior audio-visual equipment. Again, this was just a test so any constructive feedback is welcome. Thanks

  9. A documentary film about the Clintons based on the book of the same name, by Peter Schweizer. It reminds me very much of the stories told by John Perkins in his book, Confessions of an Economic Hit Man. Just follow the money.
  10. A standard deviation is not 'a bit'. Could you cite some evidence? Also, you hit on one of the issues regarding heritability. Saying the 'environmental factor is 20%' is neither valid nor useful. Joseph (2015) can explain much better than I can so have a look at the hypothetical situation he presents, below. ‘As an example of how heritability estimates do not measure the “strength” or “magnitude” of genetic influences, imagine a country in which all citizens (100 percent) carry the gene predisposing them to favism, a disease marked by the development of hemolytic anemia. Favism is caused by an inherited deficiency of glucose-6-phosphate located on the X chromosome, combined with the consumption of fava (broad) beans or the inhalation of fava bean pollen. In other words, both “beans and genes” are necessary for favism to appear. Let us then imagine that 3 percent of the citizens, all of whom are of course genetically predisposed to develop favism, consume fava beans and are subsequently diagnosed with favism. In this case, because all citizens carried the gene but only some ate fava beans, all favism variation in the population would be caused by environmental factors (fava bean exposure), and the heritability of favism therefore would be zero (0.0). Even though favism heritability would be 0 percent in this example, it obviously would be mistaken to conclude that genes play no role in developing the disorder, or that the genetic influence was weak or irrelevant. A genetic predisposition is, in fact, a prerequisite for developing favism. On the other extreme, if all citizens ate a diet that included fava beans but only some carried the gene, all favism variation would now be caused by genetic factors (carrying or not carrying the gene), and the heritability of favism would be 100 percent (1.0). As we see, heritability estimates assess variation as opposed to cause, and do not indicate the “strength” of the genetic influence (Moore, 2013).2 As another example, imagine a society where everyone (like MZ twin pairs) is born with identical genotypes. In such a society, all variation in intelligence and behavior would be caused by environmental factors, meaning that the heritability of all behavioral characteristics, psychiatric disorders, medical conditions—basically everything—would be zero. Once again, population variation and cause are different concepts.’ (p. 79) References Joseph, J. (2015). The trouble with twin studies: A reassessment of twin research in the social and behavioral sciences. New York: Routledge.
  11. This is just an assertion... Based on this view, the reported Black-White difference in IQ of roughly one standard deviation (Herrnstein & Murray, 1994) is unimportant and increasing Black average IQ scores to match White averages would not be considered a 'significant' change. Similarly, if White IQ scores dropped by a standard deviation due to some unknown environmental factor and became equal to Black scores, this would not be worth mentioning in your view. Do you consider disparities in IQ noteworthy or not? I thought you did, but based on your latest comment, it sounds like you don't. References Herrnstein, R. J., & Murray, C. (1994) The bell curve: Intelligence and class structure in American life. New York: Simon & Schuster
  12. Sorry rosencrantz, I don't understand what you have written. Schiff et al. (1982) doesn't even discuss heritability estimates and I didn't mention them, either. As I said, the study contradicts the view of Jensen (1998) and others that environmental influences can't significantly alter IQ scores. Schiff et al. compared the IQ scores of working class children who were adopted into upper-middle class families with a control group and found the former's scores to be almost a standard deviation higher than the latter's. 'In conclusion, if French children of lower-class parents were reared under exactly the same conditions as the adopted children of our study, they would obtain IQ scores and scholastic results close to those presently observed for up middle-class children. Our observations indicate that, in the population at large, failure is linked with the social class of the parents rather than with the genes they transmit, but these observations only provide ambiguous answers about: genetic differences between children of various social groups. The important point however is that, within the range allowed by our observations and by those of other authors, the answers to these latter questions are not only technically ambiguous but are also of marginal social relevance. We hope that our work will contribute in making more evident the fact that questions concerning the reproduction of social inequalities from one generation to the next cannot be answered by a genetic analysis of IQ scores, and also in making evident the even more important fact that improvements in social conditions could go a long way to ‘boost IQ and scholastic achievement’. (Schiff et al., p. 186-187) I would also like to briefly mention that the concept of heritability is very often misunderstood. There are critics (Joseph, 2004, ch. 5) who argue it should be abandoned, except for use by animal and plant breeders. I'm still trying to get to grips with how to articulate its flaws, myself, so for now I'll just share some critiques that I've found interesting (e.g. Hirsch, 1997; Joseph, 2004; Wahlsten, 1994). References Hirsch, J. (1997). Some history of heredity-vs-environment, genetic inferiority at Harvard (?), and The (incredible) Bell Curve. Genetica, 99(2-3), 207-224. Jensen, A. R. (1998).

  13. 'There is simply no good evidence that social environmental factors have a large effect on IQ, particularly in adolescence and beyond, except in cases of extreme environmental deprivation.' Jensen, 1988, p. 476) Schiff et al. (1982) reported an increase in IQ of almost an entire standard deviation compared to a control group. References Jensen, A. R. (1998). The g factor. Westport, CT: Praeger. Schiff, M., Duyme, M., Dumaret, A., & Tomkiewicz, S. (1982). How much could we boost scholastic achievement and IQ scores? A direct answer from a French adoption study. Cognition, 12(2), 165-196.
  14. Hi rosencrantz, I'm aware that you used 'you' as a general term. Joseph (2004) also has a chapter (ch. 9) on IQ in which he refers to adoption studies. One of the studies he mentions that contradicts the view that IQ cannot be increased was conducted by Schiff et al. (1982). References Joseph, J. (2004). The gene illusion. New York. Algora. Schiff, M., Duyme, M., Dumaret, A., & Tomkiewicz, S. (1982). How much could we boost scholastic achievement and IQ scores? A direct answer from a French adoption study. Cognition, 12(2), 165-196.
  15. Hi RoseCodex, When you say 'major arguments', what are you referring to? Hi Mtt, I'm sure rosencrantz is capable of explaining what he/she was attempting to do, if he/she wishes to do so, and does not need you to speak on his/her behalf. That said, I'm not really sure what 'your terms' is supposed to mean. I labelled the comment as straw-manning because rosencrantz referred to my post by implying I said something I did not say (i.e. that one 'needs' to study reared apart twins in order to measure IQ heritability). If rosencrantz's post was exactly the same but for the sentence about needing to study reared about twins, I would agree with you that the post was just supplying additional information, and would not have labelled it straw-manning. Either way, I still view it as an attempt to subtly dismiss the evidence I had already presented, without actually addressing its contents.
