Not only did only ~12% of participants get in-room HEPA (sharing common areas with the other 1,570 who didn't, with "up to 5" shared HEPAs), in-room HEPAs were only (reportedly) "usually" (which is...not a scientific unit of measure! 🙄) turned on. For "pragmatic" read "sloppy"

Third, there was low intervention adherence. However, staff reported that the HEPA filters were usually switched on and were correctly located. We considered and decided against conducting monitoring visits to check intervention compliance because the study was designed to be conducted remotely (during the pandemic), and because external compliance monitoring would have become part of the intervention, making the trial less pragmatic.

All the study did was *fail to demonstrate a statistically significant benefit* of a specific, half-measures combination of filter units - which is unsurprising when you actually read it! Of 1778 residents in "intervention" care homes, only 208 (~1 in 8) got an in-room HEPA (on the lowest setting).

Diving into the article, the title itself is directly mis- (arguably dis-)information, and the manipulative image caption is inappropriate ("monkey business" indeed). The study did (could) NOT show "Air filters don’t stop you catching infectious respiratory diseases" - a misleading exaggeration.

We are living in a dystopian state in Ontario. Look at these ads that our province is running. people don't have anywhere to go anymore - and if you aren't a moment or two away from being in the same spot, count yourself fucking lucky.

My advice to Canadians is don’t get on the back foot and attempt to defend our wildfire management across 3 million square kms to Americans. Get on the front foot and explain how decades of US emissions have contributed to Canada’s forests heating up, leading to more and bigger fires and more smoke.

His company is letting junior workers go because of their AI usage. Why? Because freshly graduated developers are TOO dependent on AI. The new developers are using AI for super-basic tasks… and that’s costing the boss too much. Now that AI tokens are expensive, companies want efficient AI use.
