One of Martin Weigel's tenets in "Good Fucking Planning" is "Be fucking numerate". I think that my numeracy is above average for the marketing sphere, but that's not the highest bar to measure yourself by.
I was reading "Double Jeopardy Revisited" (Ehrenberg et al., 1990) to try and understand why Double Jeopardy exists. I immediately grasped the qualitative theoretical explanation that relies on a thought experiment. But then the paper goes on to explain it with a statistical model. As soon as I started reading the model explanation, my eyes glazed over. I began skipping ahead, trying to find some bullet point explanations.
This is a learned behavior because, more often than not when I do try and interpret the stats I get confused. It takes me ages to wrap my head around those sorts of models and I quickly forget them. I did science for three years and it was always the hardest pat for me. I think part of it is just my make up but part of it is also just a lack of numeracy.
It's been one of my goals to improve that for a while now...
