My preferred method has been to watch court cases on YouTube where it has come out afterword whether the person was guilty or innocent. I watch these videos before i know what the truth is make a prediction and then read what the truth is. In this way I am able to get situations where the person is feeling real emotions and is likely to hide what there feeling with fake emotions.

After practicing like this for about a week i found that i could more easily discern whether people were telling the truth or lying, and it was easier to see what emotions they truly felt.

That's a really cool idea. Did you record your predictions and do a statistical analysis on them to see whether you definitely improved?

My knowledge of statistics at the time was very much lacking (that being said i still only have about a semesters worth of stat) so I was not able to do any type of statistical analysis that would be rigorous in any way. I did however keep track of my predictions and was around 60% on the first day (slightly better then guessing probably caused by reading books i mentioned) to around 80% about a week later of practicing every day. I no longer have the exact data though only approximate percentages of how i did.

I remember also that it was difficult tracking down the cases in which truth was known and this was very time consuming, this is the predominant reason that i only practiced like this for a week.
