Another very fascinating science thingy, in the realm of politics. This one is about how the right and the left perceive political consensus among their ranks and among the other side. It always feels harder to organize on the left... but should it?

Science denialism kills. Anti-vax conspiracy theory kills. This was obvious. But what are the numbers? How many more Republicans died of COVID than might have anyway? A new study has done a rigorous job answering that question, and the answer is grim. Very grim.

So many of us in this day and age are stuck at our desks, or at our homes, or both, and not getting enough movement. It doesn't take a certified science thingy person to know that's probably not great. But how bad is it? And what levels of exercise or movement make a difference? Find out!

Thanks so much for the questions! Lots of personal ones, plus some behind the scenes stuff.
It's a science thingy, but more fun! A recently published study claims that belief in Astrology correlates with some negative personality traits, like narcissism. But, is it a Good Science Thingy(tm)? Or did Mars being in retrograde cause the researchers to overstate their conclusions? It's definitely one or the other!

It's an often cited statistic that a high percentage of late term abortions are to protect the health of the mother, or due to some complication. As it turns out... this is one example of a left wing talking point that just... isn't substantiated. But importantly, it does not matter. In part 2 of our series on The Turnaway Studies, Lindsey takes us through the data on later term abortions. If you plan on trying to change the minds of pro-lifers, this is a great episode to prepare you. Learn what the data say, and why even though the traditional pro-choice talking point may be incorrect, it doesn't actually affect the argument.

What happens to people who seek abortions but cannot get them? I imagine listeners to this show know the outcomes aren't good. But the Turnaway Studies put real, tangible data into the picture. Your arguments for abortion access will be made much sharper by listening to Lindsey break down the science.

Recently a study made the rounds that sought to cast doubt on the efficacy of antidepressants. At the core of this misleading study was a real truth – that depression isn't merely a question of "not enough serotonin." But what exactly does that mean? Is this a new discovery? And why doesn't that mean that medication focused on serotonin doesn't work? Explaining this brilliantly and with singular charm is Dr. Dean Burnett!
But SIO has gained one! That's right, Lindsey has left her job as a professor and has entered our hearts as (hopefully) a full time science communicator person! We discuss the change and the reasons for Lindsey's departure.

It's part 2! This time we talk about melatonin, and then go on through the many negative outcomes associated with being a night person in this horrible morning person world. It's a lot. But there's like one good thing so that's cool.
