Am prompted to do this 🧵 following @BEERG sharing of Gove 19 April’16 speech, @kevinhorourke observation on interests & ideas & @CER_Grant observation that historians will ponder the weakness of economic interests in Brexit negs at @InstituteGC yesterday @BrigidLaffan

1/14 How do e-cigarettes (ECs) affect cigarette smoking among youth? My new paper with @FloeFoxon simulates each scenario and finds out which one best matches actual trends... https://t.co/dBB7kcnTls @jgitchell @mikepesko @SwitchFinder @jkelovuori @TobPolicy @Clive_Bates

2/14 First, let's talk about why this question is so difficult to answer: COUNTERFACTUALS. We can't know the alternate-reality answers, like which smokers would have never started in a world without ECs, and which nonsmokers would now be smoking without ECs as an option.

3/14 So, the best we can do is use fancy/sophisticated methodologies to estimate what would have happened to youth smoking rates in the absence of ECs. In our case, simulation modeling

4/14 First, we look at the declining smoking trends *that were already happening* before ECs came (~2010), and project them into the present. This is our BASE-CASE SCENARIO about what smoking trends would be if ECs were never invented. Actual trends were LOWER than this base-case

5/14 Side note about terminology: We use the term “catalyst” instead of “gateway,” because “catalyst” is more precise about the claim we are modeling (that ECs are used first, and then causally lead to smoking). Whereas "gateway" can include other mechanisms like renormalization.

I had the most bizarre experience outside of a bar yesterday, which my partner very aptly described as "toxic mask-unlinity." (A Thread.)

I was standing outside, waiting for a lyft to get home, when two cis men came out of the bar to smoke cigarettes. They're discussing the masks that folks are wearing in California at the moment because of the very dangerous air pollution from the fires happening.

I happen to be wearing one of those masks, because I think lungs are important and I like breathing. I dunno. One of the men notices me standing there, and says, "Like this f*cker right here. What is this shit?"

He goes on a homophobic rant about me, the pansy with a mask, and what a Very Manly Man he is because he's not afraid to smoke a pack of cigarettes while California is on fire. He doesn't need a mask, because something-something-heterosexual-something.

And part of me is just... impressed by the fact that this dude thinks he's Owning The Gay Libs by not wearing a mask to protect his lungs from smoke and particles in the air that are literally DANGEROUS... while chain-smoking. Outside of a bar.

THREAD: We filed RTIs on behalf of @no2uid asking the Ministry of Health and Family Welfare questions about how your personal data will be protected while you're using CO-WIN, the COVID-19 vaccination registration platform.

We got answers... kind of. Here's the new info.

1/n

Just like with Aarogya Setu, many Indians are worried that about the potential CO-WIN has to leak your data or threaten your privacy in the name of dealing with a pandemic. So, we asked the MOHFW some questions about data protection under the Right to Information Act.
2/n

In the responses we received, MOHFW said that it cannot provide us with a privacy policy on CO-WIN (?!).

Thankfully it was clarified that Aadhaar is not mandatory for registration on Aarogya Setu or CO-WIN, and that physical vaccine certificates will be provided to everyone.
3/n

The data it says it will collect will be your name, gender, date of birth, photo ID, and number.

National, State, and District level admins will have access to use the app, but there is not much further clarity on this point.

But most importantly...
4/n

The responses (or rather lack of them) related to your data privacy and protection are completely vague. We received no clear answers on which Ministries/Depts will have access to your personal data, the permissions provided, etc. This is a failure in terms of transparency.
5/n
