xkcd 870 explains a bit of the problem of trying to get people to understand how bias misleads us in research.

The mouse-over text reads –

I remember the exact moment in my childhood when I realized, while reading a flyer, that nobody would even spend money solely to tell me they wanted to give me something for nothing. It’s a much more vivid memory than the (related) parental Santa talk.

Of course this study, that only superficially addresses the question, is the final word on ________. After all, it confirms my beliefs.

Of course some stranger has decided to set up a business to give me something for free. After all, I’m a unique and special snowflake.

If you are not able to tell if I am using sarcasm, then consider that the subtitle for xkcd is – A webcomic of romance, sarcasm, math, and language.

    I’m not a fan of neither snow or frosted flakes.

    Just sayin’.
