An Excellent Explanation of the Problems with Medical Research

Dr. Ben Goldacre gives a wonderfully clear explanation of some of the problems with medical research.

How do we fool ourselves?

We selectively remember the things that reinforce our biases.

How do we fool others?

We selectively report the things that reinforce our biases.

The method of fooling others is not necessarily done with the intent to deceive. The researchers may be gulling themselves about the effect of their biased reporting.

“Positive findings are around twice as likely to be published as negative findings. This is a cancer at the core of evidence-based medicine.” (Ben Goldacre)[1]

What we see favors the positive. What we do not see is unknown, but appears to be overwhelmingly negative.

Dr. Goldacre also writes the great blog Bad Science, which demonstrates the many problems with bad science in order to educate people about good science, and he has written a couple of books on the topic.
