Homeopathy awareness

Steve Novella at the Neurologica blog just pointed out that this is the British Homeopathic Association's "Homeopathy Awareness Week".

He is right - I think we all need to be more aware of just how homeopathy can affect our lives. I encourage you to read Steve's post, which gives a quick history and an overview of what homeopathy entails. (See also the Science-Based Medicine blog.)

I also encourage you to look at what the carefully-assembled evidence from multiple scientific studies has to say about homeopathy. I recommend Ben Goldacre at Bad Science for this - here's a list of his Bad Science blog posts about homeopathy, and here's a particularly good overview. Also, anyone who can't imagine that their experiences with homeopathy could be "just placebo effects" should really listen to his two-part programme on the BBC about the placebo effect. You don't need to look to homeopathy for some mind-blowing, magical-seeming effects. There's plenty in the real world of scientific medical research. And read his book, Bad Science.

Bottom line: Real medicine is about proving something is safe and effective, and abandoning it as soon as it is shown to be either unsafe or ineffective.

Alternative medicine is about believing something is safe and effective, and rejecting, ignoring, or suppressing any evidence to the contrary.

It hurts people. It hurts people because alternative practitioners encourage distrust of real medicine in general. It hurts people because they take homeopathic treatments instead of real medicine. See for example this tragic story about Gloria Thomas Sam, a nine-month-old girl who died horribly because she was given homeopathic treatment rather than real medicine for eczema. Eczema!

Real medicine isn't infallible. But its researchers abide by strict rules of evidence: something must be proven both safe and effective before it is used in medical practice. Real medicine is self-correcting.

Homeopathy, and most alternative "medicine" modalities, are not self-correcting.

I encourage everyone - adherent, opponent, and uninterested layperson - to become a little more aware of homeopathy this week.

Novella on science

I am always looking for good, concise ways to define science and to explain why it is key to a realistic understanding of the world around us. This recent post by Steve Novella on his blog, Neurologica, opens with a pretty good summation of science and the skeptical outlook that underlies it:

There are numerous ways in which thought processes go astray, leading us to false conclusions, even persistent delusions. Skepticism, as an intellectual endeavor, is the study of these mental pitfalls, for a thorough understanding of them is the best way to avoid them.

Science itself is a set of methods for avoiding or minimizing errors in observation, memory, and analysis. Our instincts cannot be trusted, so we need to keep them in check with objective outcome measures, systematic observation, and rigid control of variables. In fact bias has a way of creeping into any observation and exerting powerful if subtle effects, leading to the need to completely blind scientific experiments. Good scientists have learned not to trust even themselves.

For more skepticism and science from Steve and company, I enthusiastically recommend you check out the Skeptics Guide to the Universe. It is a fun and informative podcast that covers all sorts of cool and unusual topics - from current science to skeptical thinking to evaluating paranormal claims.
