You can shorten the table by about half if you eliminate the negative logarithms by using the laws of logarithms.
For example, −20 decibles in terms of probability is just 100% - (The probability corresponding to +20 decibles), and the odds ratios simply occur in reverse order. That is 20 db = 100:1 and −20 db = 1:100
I’d give most people who even attempt to assign probabilities to their beliefs in the first place enough credit that they can perform very simple arithmetical operations.

Given the chart is for those who aren’t mathematically inclined, I’d suggest this might not be a great idea.
