If you haven't gotten it yet, that achievement is for skipping the minigame. You first need to fail the minigame twice in a row to unlock the skip option. The fails are saved through reloads, so you can just save at the Reason/Instinct choice and reload to it immediately after each fail.
If you need any help with other achievements, I posted a guide to all of the achievements for each route further down in the comments here.
