First, I'm sure most researchers "work hard and mean well". If not, they'd be much better rewarded in almost any other line of work. I agree that the system is not perfect. However, I would also have a hard time saying that double blind is the perfect system (or even necessarily better). There are many reasons why it would be worse than the current system.
But this isn't to say that the system of publication is perfect. Why don't we innovate more in how we organize research on a macro level?
