Last year, @NIMH_RDoC @NIMH commissioned a report from us @McLeanHospital (w/ @DanielGDillon @JustinBakerMD @laurenrutterr) re digital cognitive assessments for field test use, from >300k TestMyBrain participants. That report is now available! psyarxiv.com/dcszr/
Key findings: First, (1) *RELIABILITY IS A MAJOR ISSUE*, particularly for tasks from basic science / experimental traditions, built for detecting within person diffs and where reliability for between person is rarely reported. #psychometrics <- probably not trending
Second, (2) measures of negative valence / emotion (e.g. threat processing) and positive valence (e.g. reward sensitivity) usually not built for large-scale mobile assessment: technically, psychometrically, or re engagement - important for projects like @AllofUsResearch
Third, (3) Device variability is an issue for #digitaltechnology, particularly mobile cognitive assessments. Devices differ! Measurements of response time latency can differ by as much as 100ms between different smartphones. See also tandfonline.com/doi/full/10.10…
Fourth, (4) and can't stress this enough: participant engagement matters. We have N=300k in #citizenscience because the participant is a key stakeholder. And (surprise! win-win!) tests with better psychometric properties had better participant ratings and better retention!

@realDonaldTrump Trump nominated this guy to a federal judgeship. It came out that he’d blogged favorably about the KKK. He had to withdraw. So he went back to working at the Justice Department, where he was—wait for it—in charge of vetting judicial nominees. bit.ly/2MD2iBZ
@realDonaldTrump In its first year, the Trump admin launched an across-the-board assault on our nation's civil and human rights. This is why we must all continue organizing to fight for the kind of country we deserve.

"I want to warn the world about an unprecedented danger that’s threatening the very survival of open societies.

…I’ll focus on #China, where President #XiJinping wants a one-party state to reign supreme."

"Xi is trying to consolidate all the available info about a person into a centralized database to create a 'social credit system'..people will be evaluated by algorithms that will determine whether they pose a threat to the 1-party state. People will then be treated accordingly."
"#China is not the only #authoritarian regime in the world, but it is undoubtedly the #wealthiest, #strongest & most developed in machine learning & #AI.

This makes #Xi the #most #dangerous #opponent of those who believe in the concept of #OpenSociety."

We need to place gender essentialism (the notion that women's oppression is innate and natural) in a wider context - a long lasting global recession with deep political and economic uncertainty and pain.
History teaches us that most authoritarian regimes begin by deceiving people that they are left wing or progressive. History shows us that totalitarianism utilises student groups to gain power. See my thread on this:
Authoritarianism usually starts with trying to control women. As Valerie M. Hudson argues 'it’s vital to remember that for most of human history, leaders & their male subjects forged a social contract: “Men agreed to be ruled by other men in return for all men ruling over women.”

I believe one way we can create a safer future is to understand the various tactics abusers use to deceive. I hope the last year has increased our discernment and courage to confront. To that end, here's a thread of deceptive tactics abusers might use to groom their targets:
Abusers might use their position of power to grant favors and give gifts to those with less power. Attached to the favors and gifts is the unspoken expectation to do whatever is asked of you. Past favors are used as guilt trips when demands are not met.
Abusers can use their power to offer help in ways that are beyond necessary. This over-helping can be a form of manipulation in which you and others are made to believe that the only way you can succeed is with their help, which makes you dependent upon their help.

So that's FOUR people unceremoniously stripped off of Mueller's team. Peter Strzok, Lisa Page, Sally Moyer, and one other person as yet unidentified.

Remember when I told you people were INVESTIGATING THE INVESTIGATORS the entire time Mueller was forming his team? 🤔
Mueller has not only found nothing he can use to hurt Trump with, he's had 4 people pulled off his team in the last year. And we now have a report that altered 302 interview forms are being investigated by the OIG.

A lot of people think the OIG IG report on the Hillary Clinton Email investigation, is just about how it was sabotaged so she could walk away from exposing/mishandling classified intelligence.

While it is that, it also the gateway into all her pay for play schemes as SecState.
And the biggest pay for play scheme Hillary & Co. were involved in was the massive Uranium One scheme.

Never say the Clintons are stupid. They learned from the mistakes they made in the 1990's.

No bags of cash delivered by businessmen personally this time.
In case you don't know what I'm talking about, the mistakes the Clinton's made with their pay for play schemes in the 1990's, here's a quick refresher:
