Look at: The mask paper that was talked about but was never published because the results were inconvenient. Anytime statistics blow up a narrative.
The Swedes actually followed the science by listening to all the recommendations prior to the pandemic. The best example of this is the WHO or the CDC prior to the outbreak having published and peer reviewed papers that said lockdowns do not work.
Now the next comparison to do is that the approaches of all the other countries followed lockdown. Sweden did not. They then proceeded to have no significant death differences between countries. Seeing that, there will be significant mental differences and knock on effects from the different reactions.
Ultimately, the Swedes got it right by not panicking, followed the non politicized science, and keeping calm and carrying on.
