This thread documents a persistent pattern of harassment against me. It gets tiring after a while defending why I've been speaking out against the behavior of this individual so I decided to document what's been going on.
This account has 140k+ followers. I blocked it in June but it has been creating posts with screenshots of my tweets. This has caused hundreds of trolls over the last five weeks to enter my comment sections and to tweet at people I interact with. Often their insults are racial.
As you read these posts, please consider that each one caused massive numbers of angry followers to seek out my account and harass me.
When speaking to me directly, the animosity is more clear than in the tweets to the account's timeline. Note, I have never returned any insults. I replied by stating my scientific credentials and making technical arguments.
"You can't be this stupid, which means you're completely dishonest."
One of the things I hate most about the cult of IQ is it leads to lot of magical thinking about how the brain works. There’s absolutely nothing shameful about relearning things you use to know.
Research shows forgetting is a normal part of human cognition.
The way to combat the natural tendency to forget is to relearn or retrieve the memory at regular intervals which is known as “spaced repetition”.
Relearning takes the strength of the memory back to 100% and the rate of forgetting is slower the next time.
Infographics of this dataset have been kicking around on the internet for years. It is an insult to real scientists everywhere. For every 10 likes, I will post a new ridiculous fact about how fake and ridiculous this "data" is.
They report data on 185 countries but *104* of those numbers (more than half!) are based on *zero* data collected from people from that country. ZERO.
Rather than acknowledge this lack of data, they decided to guessimate based on surrounding countries.
The IQ estimate for Equatorial Guinea was based on kids in a home for developmentally disabled kids living in Spain. Not even their home country. Spain.
People are getting thousands of likes for spreading this misinformation about sex differences. Let me explain why this interpretation of the data is wrong. 🧵
If you think 100% accuracy is too good to be true, trust your instincts.
The version of the model shown in the plot was basically fed the sex of the participants. That’s why it’s achieving 100% accuracy.
When the model was tested on a subset of people from the same dataset that it had *not* seen previously, the accuracy fell to 90%.
I keep seeing this Huberman clip all over my timeline so let’s use it as teachable moment to learn some statistics.
The basic mistake is not taking the people who are already pregnant out of the pool of people who could be pregnant the next month. Of the starting 100, fewer and fewer will remain each month.
It’s a little tedious to keep track of what number of people aren’t yet pregnant on each round, and then take 20% of that, and then add up all the pregnant people in each round.
