I have found that lie detection is an extremely useful skill to possess. A lot of tactical problems can be abated or avoided altogether with this skill. We understand how important awareness is, lie detection done right is close to a super power as you are likely to realistically get. It can tell you what is going to happen in the future so you can avoid it. It can also give you an accurate account of what has happened in the past. It can uncover threats of all kinds and get you in front of big problems. Does anyone develop and practice lie detection? I find I use this skill often for big and little things to help keep me safe.
