People Trust Peers, Not Science

This is depressing, but not surprising, I guess. Three psychological studies have come out recently all saying about the same thing. People trust their peers and tend to distrust authority (the government) and scientific information.

I heard about this on The Skeptic’s Guide to the Universe, episode 254, from May 26th. If you want to listen to Dr. Steven Novella talk about the three studies, start around the 23:30 minute mark. This segment goes to about 35:20, but the whole episode is good, of course.

The attitudes of parents toward the MMR vaccine and autism: The study concluded that parents had a significant bias toward believing information that they heard from other parents. The parents were mostly affected by their peers, and did not seem to be affected at all by what the scientific evidence said, and they seemed to inherently distrust information that came from the government. Not a surprising result.

Raising a general level of scientific literacy would be the best thing we could do to help this mess we’re in. My fear is that people are so anti-science and anti-intelligence these days that I don’t know how we could go about it, that people aren’t interested in learning anything that goes against their narrow world views. Another thing we could do (as recommended by Steven) is to change regulation so that it’s rational and evidence-based, not based on public opinion. Read the rest of this entry »

What Level Of Woo Would Make Someone Undateable?

Here is a question for you. What level of woo would make someone undateable? What about unfriendable? Do you have a limit that you’ve drawn in your life or do you have a lot of woo woo people around you that you interact with? How do you get on with them? Do you find it difficult? Do you argue with them or are you silent about your woo disbelief?

Woo can be defined as anything supernatural, irrational or lacking in evidence. So it would include religion and any kind of pseudoscience.

On a side note, is there anything that could be defined as woo that you still believe in? If so, why?

For me, I’ve somehow whittled down my friend list from all woo-lovers to all skeptical atheists. I didn’t do this deliberately, but I guess with my skeptical talk and constant questioning (not aggressively, but I really did question all the woo I previously embraced), my woo-loving friends all went their separate ways and avoided me within months of when my quest for knowledge began.

I didn’t have many friends for awhile but then found the Morgantown Atheists where I found several people that have become good friends. Also, having HDC has let me meet new people who were rather like-minded as well.

With extended family, I still have to deal with woo, both religious and supernatural. They know Butch (my awesome husband) and I are die-hard atheists so we have come to an unspoken agreement that we don’t talk about religion. Or politics just to be safe and have nice dinners together.

I think I’m lucky in most respects. My skeptical atheist friends keep things lively by being smart and reason-based (most of the time, we’re not perfect, of course). And my extended family gives me an occasional glimpse into woo-land so I get to see what the majority of people are dealing with and believing. It’s enough.

Justice Late Is Better Than None At All

The AP has an article titled Britain bans doctor who linked autism to vaccine.

This is great news! My first question is why it took Britain so long to make such a move. My second concern is that he will just come back over here where he is worshiped by idiots like McCarthy and her ilk. And my third concern is people will still worship him and continue to avoid getting their children properly vaccinated, causing suffering and even death for innocent kids everywhere.

LONDON — The doctor whose research linking autism and the vaccine for measles, mumps and rubella influenced millions of parents to refuse the shot for their children was banned Monday from practicing medicine in his native Britain.

Dr. Andrew Wakefield’s 1998 study was discredited — but vaccination rates have never fully recovered and he continues to enjoy a vocal following, helped in the U.S. by endorsements from celebrities like Jim Carrey and Jenny McCarthy.

“That is Andrew Wakefield’s legacy,” said Paul Offit, chief of infectious diseases at the Children’s Hospital of Philadelphia. “The hospitalizations and deaths of children from measles who could have easily avoided the disease.”

Wakefield’s discredited theories had a tremendous impact in the U.S., Offit said, adding: “He gave heft to the notion that vaccines in general cause autism.”

In Britain, Wakefield’s research led to a huge decline in the number of children receiving the MMR vaccine: from 95 percent in 1995 — enough to prevent measles outbreaks — to 50 percent in parts of London in the early 2000s. Rates have begun to recover, though not enough to prevent outbreaks. In 2006, a 13-year-old boy became the first person to die from measles in Britain in 14 years.

“The false suggestion of a link between autism and the MMR vaccine has done untold damage to the UK vaccination program,” said Terence Stephenson, president of the Royal College of Paediatrics and Child Health. “Overwhelming scientific evidence shows that it is safe.” Read the rest of this entry »

The Secret Is Still Bullshit

The Secret, which is all about the Law of Attraction (not a real law, or even real), is still bullshit. But Elizabeth found a great video from Australia that will make you laugh. It explains how The Secret works. It’s about 7 minutes long:

Notice how in the demo clips it’s always about some materialistic thing like a bike or a necklace? How shallow and self-serving! Why don’t all believers in this stupid lie wish for world peace or clean drinking water for everyone? Or everyone to be disease free? Instead they have to have a new Shiny. Pathetic!

Oh, and see the waves of rays coming out of the peoples’ heads? That doesn’t happen. That’s a special effect. So when you wish for something your thoughts don’t actually leave your head. Just in case you were wondering. Don’t believe me? Ask a neuroscientist. They have proof your thoughts don’t leave your head by magic (they only leave your head when you speak, write something down or perform an action based on those thoughts)

Oh OH! And when you ask for something, then believe it’s already yours, there’s no invisible man in the sky that says to you, “Your wish is my command.” You know that, right? The Universe doesn’t have a log of every time you wish for that new Ferrari. It doesn’t wait for the wish requests to reach 1,000 before it has it shipped to you. (Don’t move your house because it will get delivered to your old address! LOL!)

Information IS Beautiful!

Stumbling around the interwebs, I found a site that I think you might love. It’s called Information is Beautiful. David McCandless takes all kinds of data and ideas and visualizes it in appealing ways.

The one I found that I thought was amazing was Snake Oil?: Scientific evidence for popular health supplements. (That link takes you to the interactive version. See the static version here.) On the side is a show me button that flies out a list of uses and types of supplements. Choose what you’re interested in to filter the results. The bigger the bubble, the more popular the supplement is. The higher on the chart, the more evidence there is that it works. Notice how many bubbles are below the Worth It line. Remember, the supplements are only good for the conditions listed inside the bubble, which you can see by hovering over it.

What David says about the evidence:

We only considered large, human, randomized placebo-controlled trials in our data scrape – wherever possible. No animal trials. No cell studies. Many of the health claims made by the $23 billion supplements industry are based on non-human trials. We wanted to cut through that.

This piece was doggedly researched by myself, and researchers Pearl Doughty-White and Alexia Wdowski. We looked at the abstracts of over 1500 studies on PubMed (run by US National Library Of Medicine) and Cochrane.org (which hosts meta-studies of scientific research). It took us several months to seek out the evidence – or lack of.

The information is generated from a Google Doc, so when new research comes out it can be easily updated. Very cool indeed. The data has web addresses to the source of the research so you can see it for yourself. It’s not just anecdotal evidence.

David also has a chart on caffeine and calories. He even shows how much exercise it will take to work off that large iced mocha you had for breakfast.

He does two interesting charts about politics. The Left vs the Right. A world version and an American version. These are chock full of information.

His 2012 chart is also great. The left describes the believers, the right describes the skeptics, with information refuting what the believers say. Sources are listed at the bottom, and are available in a Google Doc.

His climate change chart shows global warming deniers vs the scientific consensus.

He has many more on his site as well. That’s just a few of my favorites.

Answering Paul’s Questions

A person named Paul commented on HDC on GMNightmare’s deconversion story and I thought they were interesting questions. Both Johnny and GMNightmare already gave long answers, also worth noting, instead of letting it get lost in comments. And I added my 2 cents on at the bottom.

Here is Paul’s comment:

I have a couple of questions that I would like answered, and you seem like the type to answer questions. First of all, what are your thoughts on supernatural phenomena (weird stuff people claim happens, i.e., someone’s ear being cut off, and growing back on)? Is it all just a big hoax?

Secondly, I know that evolution details how the earth came to it’s present state, and the big bang, (do they still call it that?) started all that, but what could have caused the big bang? And how did whatever caused the big bang come into existence? As far as I know, science clearly states that nothing can be infinite, and all things have an end and a beginning. So, if nothing is infinite, than how did the universe get started? Wouldn’t something had to have caused time to exist first, something that wasn’t governed by time, and so couldn’t even be described by adjectives like infinite?

I just have these questions, and no one can really answer them, except with some lame thing like “It just goes on and on”. And what does happen when we die? I know our bodies clearly decompose, we can see that much easily.

But what about our consciousness? It seems to me that consciousness is somewhat of a mystery in and of itself. Scientists can make a body, and they can put blood and oxygen in it, but yet they can’t make it live? So, if a consciousness isn’t something like a body, something that decomposes, what happens when the consciousness dies? Does it really just cease to exist? I can’t even imagine not existing. It just seems so foreign, to not exist.

Lastly, I don’t really get the term “gnostic atheist”. From what I’ve read, gnostics claim to “know” something, that other people don’t. So, if you’re a gnostic atheist, does that just mean that you “know” hands down, that there is not, and has never been, any kind of god?

First, here is Johnny’s reply:

I’m sure GMN will have a response; but I just feel the desire to chime in. Read the rest of this entry »

Conversation With Anne About Religion, Truth, Science and History

The other day I got an email from Anne which I will post below. She asked some basic questions and I thought I’d share my answers with you (with her permission, under a pseudonym for her privacy). So here is her email:

Well I am new to religion totally as neither of my parents knew what to believe so they taught me nothing. I have so many questions and not nearly enough hours to google! lol jk

If you dont believe in a higher being such as God like the Christians what do you believe? (***Now please dont think I am questioning your beliefs I simply need a better understanding of what you hold to be true in this world.***) Do you believe that things happen simply because we choose that is how it should or is there a force behind events? I have gathered you believe in evolution but how were monkeys first placed on earth? And then how was earth created? I believe it is truely unknown to begin with but do you have a theory?

My reply:

First, question everything. Don’t take my word for it. Research everything yourself.

I have a couple of questions for you.

Your parents taught you nothing about religion? So you picked up bits and pieces as you grew up from other people? That’s interesting. Are they atheists then? Or do they just never talk about religion? Perhaps it just doesn’t seem like an issue to them? I am curious if they’ve said anything to you at all. What kind of school did you go to? Did you go to public, private or home school? In which state? And how old are you?

Raising a child without teaching them anything is not what I’d consider ideal. My idea of a great foundation for a child is to teach her how to think critically, to think for herself. I recommend teaching a child about all religions from around the world and throughout human history, then asking questions to help the child form her own understanding about it. I would also share my personal opinion on the subject. But most people don’t raise their kids to think for themselves.

It sounds like you’re searching for something to believe in, but I would ask why you need to believe in anything that isn’t real? Read the rest of this entry »
