An old bit in Harper's Index quoted that the average number of time you have to taste something you have an aversion to and develop a taste for it is 12. Like most statistics in Harper's Index, the veracity of that number is questionable and amusing. However, the idea that you might just need to try more than you think is what's thought provoking about citing this probably fallacious statistic. (Harper's Index was basically a nicely arranged list of thought-provoking cited statistics you weren't supposed to take at face value, arranged in a way to create a narrative arc.)

Another piece I read on this topic was aimed at foodies. The thrust was basically: "You're trying to broaden your horizons by trying different obscure dishes from other cuisines. Why not revisit the foods you hated as a child? I used to hate eggplant and thought it was slimy and now I love eggplant."

There's something compelling, in matters of taste, about addressing a huge blind spot you have been avoiding tackling instead of hyper-specializing in your chosen niche.
