1) Our new genome-wide association study for IQ (nature.com/articles/s4146…) included the peripheral result that some genes linked to higher IQ are also linked to higher likelihood of poor eyesight. Here's how the media bollocksed up the coverage of it in almost every way:
2) The Telegraph turned a genetic correlation of .29 into "those who were more intelligent were nearly 30 per cent more likely to have genes indicating they require reading glasses" (!?!?): telegraph.co.uk/science/2018/0…
3) The Telegraph also described a sample size (44,480) that's nowhere near the actual sample size of the study (300,486). None of us have any idea where this number came from. It was repeated in several other stories. ¯\_(ツ)_/¯

"Heritable" 👏 doesn't 👏 mean 👏 "immutable" 👏

(I genuinely think a big chunk of the angst about genetic studies would evaporate if people understood that)
This study found that myopia is *85%* heritable. AND YET... if you put on the right pair of glasses, your myopia is (effectively) gone. iovs.arvojournals.org/article.aspx?a…
The whole argument about the difficulty of raising IQ isn't due to IQ being heritable. It's about the fact that we just don't know that many ways of raising IQ - there isn't (yet?) the equivalent of "putting on a pair of glasses".

Thread -> In publicity for his new book on depression, Johann Hari has repeatedly made the following claim: "between 65 and 80% of people on antidepressants are depressed again within a year". He says it in this extract: theguardian.com/society/2018/j…
Here he is saying it in a video, right at the start:
Disgracefully, no source is given for this alarming claim. Maybe there's one in his book, which comes out tomorrow. In the meantime, I took a quick look at the recent(ish) meta-analyses of research on relapse rates after/during antidepressant use.

"There is proof the footage of the alleged chemical attack in Syria was fabricated." - Mother Agnes Mariam el-Salib
The warmongers keep repeating false flags to start wars. Notice they keep repeating ALLEGED in their accusations as they try to justify wars.

ALLEGED - (of an incident or a person) said, WITHOUT PROOF, to have taken place or to have a specified illegal or undesirable quality.
