Dangling the idea of a 50 year mortgage as a solution to home ownership relies completely on assuming that the average American can not do basic math
And sadly, that might not be a bad assumption 😐

I had the honor of seeing Watson's racism on display first-hand
In grad school, he was the invited guest for a speaker series I ran with other students. At dinner he looked my Latina classmate in the eye and said "Your people don't usually have the work ethic to succeed in this field!"
Bad guy.

In 1953 James Watson revealed the double helix structure of DNA
He spent the rest of his career revealing how great scientists can be awful people

Australia has so much electricity from solar power that it is going to start offering free electricity to everyone for at least three hours during the day as the wholesale price of power goes negative

Australia's extensive solar power penetration makes so much energy that the government wants to offer free electricity at peak hours.

It's easy (and usually fun) to dump on pundits. But I think both of these things can be true
1. Very few Dems think algebra is racist or banning plastic bags is a big priority
2. Lots of people *think* D's are obsessed with these things because being a Democrat is historically unpopular and uncool

I don't think it helps the debate about what Democrats should do to pick an obscure thing that some Democrat somewhere may have said -- like on teaching eighth grade algebra -- and then attribute it to Democrats generally.

More people need to realize politics has devolved into sorting people into buckets and keeping them there
1. Pick position (e.g. vaccines r scary)
2. Signal "if you're one of us, you must believe [1]"
The reality of the position doesn't matter to these people. It's all just shepherding for power

When I say that being anti-vaccine is a political identity now I mean literally. Look at the divide between MAGA and non-MAGA Republicans.
During COVID the Virality Project documented the extent to which political influencers who’d never commented on 💉 before got deep into the topic on all shots.

We can save RFK Jr some time here, because we already know a lot about acetaminophen and autism!
There’s no increased risk of autism from use of this drug. This isn’t based on some small study. It’s thanks to a beautiful study of literally millions of children…

The loss of any life to political violence is a profound failure of humanity’s potential. We must resist the gravitational pull toward dehumanization and vengeance no matter how much we disagree with someone

The board is wrong. But politics is a game of perceptions more than it is about reality (which I wish wasn’t true but 🤷♂️). And plenty of bad actors have been able to make these perceptions more salient/popular, and retcon reality in order to erode trust in institutions.
None of this is an accident!

The Washington Post editorial board is essentially endorsing the backlash against public health, and only Florida took it too far. This is pandemic revisionism at its worst, and completely erases how layers of public health protections did so much to save lives before vaccines were available.

When you remember that much of the modern GOP mission revolves around weakening institutions by eroding our trust in them, this seems like a big win for them
Only 26% of Americans say they "somewhat" trust RFK Jr's medical advice. The rest do not.
Those are horrifically bad poll numbers.

The more alarming trend is that since 2021, conspiracy thinking has noticeably increased and agreement with science has decreased
