You Can't Trust Science!

Here is an objection to science I often hear from some of my students whenever some other students mention how science has disproved some religious claim: 'scientists are always changing their mind about their claims regarding the way the world works, and if they're always changing their mind, then they can't really be trusted.'

Of course, since scientists normally change their minds when new evidence contradicts something they previously believed, we ought to regard that self-correcting mechanism as one of science's strengths, not one of its weaknesses. If you keep believing something which is consistently contradicted by the evidence, you're not admirable... you're just stubborn.

And yes, in my book, breast implants are proof that science and technology can sometimes kick nature's ass :)
