Introduction
You're listening to the Skeptics' Guide to the Universe, your escape to reality.
S: Hello and welcome to the Skeptics' Guide to the Universe. Today is Wednesday, September 22nd 2010, and this is your host, Steven Novella. Joining me this week are Bob Novella
B: Hey everybody
S: Rebecca Watson
R: Hello everyone
S: Jay Novella
J: Hey guys
S: And Evan Bernstein
E: Happy equinox!
J: Sure
R: Is it?
E: That would be the Autumnal equinox
S: Autumnal. Do not try to stand eggs on their ends though on this one
R: No, this is the one you can stand chickens on their heads, I think
(laughter)
S: Right
E: I can't stand chickens
B: Now wait, Autumnal equinox, does that mean the- that means the sun is over the tropic of Capricorn? Or Cancer?
E: The equator
S: That's right
E: The solstices are the tropics
B: Ah
J: Ok
S: It means we're entering the bottom half of the analemma, that's what it means
B: Yeah
R: The what?
B: The figure eight the sun makes in the sky throughout the year. Remember that, Steve?
S: Yep
E: That's cool

Penn State university news: Losing your religion deemed unhealthy
S: Rebecca, can you tell us about this crappy study looking at health and religion?
R: I would love to, Steve. Yes, sociologists at Penn State have published a study that suggests people who leave strict religious groups are unhealthier than members who stay in those groups. Now, it's self-reported data the researchers pulled from a survey that's been conducted annually, or biannually, since 1972, and encompasses more than 30,000 total cases. 40% of members of strict religious groups apparently reported that they were in excellent health, and this was compared to 25% of those who switched religions who said they were in excellent health, and 20% of those who left religion entirely who said they were in excellent health. The researchers came up with some ideas as to why they think this happened. I'm a little skeptical of some of their guesses
E: Very good, very good
R: Mildly. One of the first things mentioned in the press release was that strict groups often discourage unhealthy behaviors, like alcohol and tobacco use. But, of course, we have another study that shows that moderate alcohol use is healthier than abstaining, and also these groups don't necessarily restrict things like bad food, and things like that. And there are plenty of other things that could make you unhealthier in those groups.
S: Yeah, but remember, this was just people's perceptions about their health, not really any direct measure of their health. So even if it is healthy to drink moderate amounts of alcohol, if people think it's unhealthy, they may report their health as being worse. Right, this is all about what people think about their own health.
R: Yeah, the mere fact that this is self-reported data puts everything kind of into question, I think. Especially when- that's not to say that self-reported data is useless, but when we're talking about health, and we're making broad conclusions about the health of people who leave religious groups, I mean, shouldn't we at least have actual, verifiable, evidence of what their health is like? And yeah, we don't have that here, we just have peoples diagnosing themselves.
S: Yeah, "Do you feel healthy?". That's basically…
R: Right
S: … the information we have
R: The researchers go on to also suggest that maybe these groups provide more hope and positive thinking. Which again, I think is BS. I think that it can vary greatly depending on what religion we're talking about, what members we're talking about, there are certain members of these strict religious groups that, you know- I mean positive thinking doesn't really work very well if you're, for instance, in a fundamentalist Mormon sect, and you happen to be a 13 year old girl. That can be kind of a downer. But of course, these aren't the people that are being surveyed, I'm sure. So I find that a bit troublesome, but when they're talking bout that point, they expand on it a bit by saying that when you leave a group, you can lose friends and social support, and that, I think, makes sense. When people leave groups, like thinking of the Amish, or Mormons, or Scientologists, these groups actively force you to cut all ties with your loved ones, your friends and your family, so that it means you're left destitute, possibly, especially if you were a woman who was married to someone who provided all your income, you're left with nothing, and on your own. So that can have a serious effect on your health. But all that says to me really, is that we need to focus on improving resources for people who leave cults and other strict religious groups, helping people in the de-conversion process, and offering them a network and a safety net. That's the only thing that I took from this study that was any worth at all, and even that was tenuous.
S: Yeah, there are a number of ways to look at this study. I think this is one of the studies where scientists are looking where the light is good, not necessarily that this is a great study design, but you have this data sitting there - it's tempting to comb through it, pull out correlations and publish it, right? It's kind of a quick and easy publication. So I think that's what they're doing. And then they're running the entire gamut of possible cause and effect relationships to explain this correlation they found. They also said that it's possible that people who become unhealthy can't keep up with the social demands of the religion, and then fall out of it for that reason.
R: Right
S: So they're basically throwing everything out there, yeah
R: And people who fall out because of poor health, they said, because they're not able to go to the meetings and participate anymore
S: Yeah
R: Or they just get angry that all the praying isn't working
S: Yeah, right. There's so many confounding studies in a study like this, it's hard to say anything. And I think the researchers know that, but again, the data was there, so that's why they pulled it. And also, statistically I'm a little bit dubious of the fact they found a statistically significant effect only for the strictest groups. Does that mean they looked at other religious groups and the effect was not statistically significant? And did they account for multiple comparisons? I'm not sure about that
R: Yeah, and to be clear, you know, we're not talking about- they're not talking about just atheists in general, they're not saying atheists are unhealthy, they're talking about these people who leave these fundamentalist, these strict religious groups, so it doesn't really- I'm a bit afraid of this getting reported in a way that…
S: Yeah
R: You know, that takes it out of context and expands it to include all non-believers, which it simply doesn't address
S: This was actually switchers, not necessarily people who become atheists, this is people who could switch to a different religion.
R: Right, they split it up between those two. They did say that there was a statistically significant difference between switchers and people who left religion entirely, that being a 5% difference. Well, 25% saying they were in excellent health, who switched religion, and 20% who left religion entirely. They said that was statistically significant, but it is slight, when you're looking at the huge difference between members who remained in the group, and those who left.
S: I did look at just what else has been published on this question, and it seems to me, just looking at 20 or so studies in PubMed, that there does seem to be a consistency in the published studies that having a social network has health advantages, and losing your social network is a bad thing. But when you separate that variable out from religiosity, that the religiosity itself doesn't seem to have a health benefit, it's just having the social network that goes along with being religious, that's the thing
R: Right, and that's basically what I said
B: That's what it all boils down to
R: Yeah, is that we need to provide- if anything we could take from this, it's that we need to provide a better social network, a better support network for people who leave
B: FACEBOOK!
(laughter)
R: There's always Facebook, it's true
S: Right
