It would be disingenuous of me to claim that my current desire to change careers is motivated by the career and not by own circumstances, and the problems with me are detailed in previous posts. But still, the current state of the profession doesn't help. It is one thing to work very, very hard to get to that first hint of a great discovery. It's another to work very, very hard to ensure that your science is of exceptional quality, especially when no one's looking that carefully. When this is the case, it's easy to feel like the people winning the game aren't doing so by playing within the rules. A recent commentary in Nature (483:509) alluded to the large number of sloppy mistakes that are creeping into papers. When the goal is to push out publications as quickly as possible, the ugly reality is that the incentives are often in the wrong direction: being sloppy can work to the benefit of the laboratory publishing the paper.
Two high profile examples of this have recently appeared: the finding that the effects of an "anti-aging" gene disappear when the controls are done carefully (Nature 477:482), and the whole debacle surrounding the infamous "arsenic bacteria" story. Now that the refutation of the conclusions of the original paper have been accepted, it's worth taking a step back and recalling that NASA originally pitched this as being relevant to the study of extraterrestrial life. There isn't any bigger splash you could make with the popular press. When the paper was made available and it was clear what it was really about, I think the public was somewhat disappointed. Let's just be clear that this had nothing to do with extraterrestrials. The idea that a living thing using something other than the CHNOPS elements (carbon, hydrogen, nitrogen, oxygen, phosphorous, sulphur) has anything to do with alien life is frankly confusing.
