Regarding the filtered evidence: we have researched and are offering the actual evidence that scholarship in psychology and cognitive neuroscience have shown as contributing to gaining a greater sense of personal meaning and purpose. This includes, as the workbook describes, 3 things: 1) Reflecting on the question of purpose and meaning in life 2) Developing strong community and social bonds 3) Serving others, in a variety of ways.

Different societies, whether authoritarian or democratic, provided opportunities for these activities in different ways. I certainly hear what you're saying about communist countries and organizing fun. I experienced that myself, as I know you did as well. Yeah, their fun wasn't so funny for brainy people like us, but for the average citizens, my research shows it was quite a lot of fun. For a brief overview of what my research shows about how the USSR did so, here is a 6-minute video I created on this topic. The point is that there are a variety of ways to find purpose and meaning in life, and the workbook encourages people to be rational agents about one's search for purpose and meaning.
