When disarming traps, I usually use the most rogue-like member of the party- typically my Grave Robber or Bounty Hunter. It seems to work more often but this might just be confirmation bias.
I can't find any visible stat which would affect this. Aside from changing which character risks getting hit, does using a different character to disarm a trap increase the chance of success?

When looking through your party's stats you can see their trap stat. The higher the trap stat the better the chance of a successful disarm.
