Understanding is Not Enough

Just a short quip:

The hard part is not recognising the existance of -- and understanding -- our perceptual and cognitive quirks, limitations and biases, the hard part is in recognising the situations when they apply to ourselves.

Or perhaps it would be better worded slightly differently (changes highlighted):

The hard part is not recognising the existance of -- and understanding -- our perceptual and cognitive quirks, limitations and biases, the hard part is in learning to recognise the situations when they apply to ourselves.
