Your Data Are Probably Biased And That's Becoming A Massive Problem by @Digitaltonto via @Inc

Nobody sets out to be biased, but it's harder to avoid than you would think.

I really liked this and he makes some very good points.  I believe if you are aware of bias and the ways it can happen you are part way to get around it as you can look out for it and adapt your ways of working to avoid it.  Peer reviews are also great as the more eyes on a problem the less chance you are all going to have the same bias - especially if you are a from different backgrounds and skillsets.
