Yout point, "While some trainings have been shown to alter participants’ beliefs or attitudes in small ways, they have little to no impact on participants’ behavior," isn't true. Behavior is modified much the same as an incoming mortar round. The participants now know when it's time to hold their tongue and wait for the debris to settle. I have been made to sit through meetings on How to Have Meetings. Those meetings were just plain unproductive, and, while the organizers suggested that you should ask, "Why am I in this meeting?" nobody let me leave when they couldn't 'splain it to me.
