That's how it's supposed to work, and largely does in the long term. And yet you wouldn't deny the influence i'm talking about exists would you? Ben Goldacre says alot about how science is skewed by industry in Bad Pharma and he's quite hard to argue with (and certainly pro-science). It's that reality i'm talking about which i think exists across other areas, especialy in 'industry' research. I won't give it any sort of free pass just because it has the appearance of science; i do think the wider 'science' will work it out in the long term through the scientific method, but in the meantime there are fortunes to be made (and unfavourable results to be binned).
