The 5th social trigger is Equal Participation (and Skill Level). Nothing detracts more from group flow than people who aren’t pulling their weight. The opportunity to contribute equally is vital.

If you are looking for the key to equal participation then you may well benefit from analysing skills. To be on the safe side developing skills often increases the odds of equal participation.
