(It's an approximation under chi-squared and an exact calculation under Fisher's exact.) I'll address chi-squared and it will generalize to Fisher's. The issue here is the premise.

When the p-values tend to be small, the test statistic X will be large, which suggests that the null hypotheses are not true for every test.
