An amazing book, even for those who are not Jewish.
Rabbi Kalmenson has managed to distill the essence of the beloved head of the Chabad Jewish community, Rabbi Menacham Schneerson, into an easily understood and internalized book.
Positivity Bias, at it's heart, is a way to recontextualize or reframe one's paradigm in order to adapt to adversity and operate more efficiently amidst the stress from that adversity. Rabbi Kalmenson has taken broad and specific subject areas, and addressed each in fascinating detail, one subject per chapter, so that they are easy to read, and can be read or bypassed to focus on any specific issue.
While some of the chapters and topics are specific to the Jewish community, "Who is a good Jew" for example, the vast majority are applicable to humanity in general "Fight Evil, Do Good" and "Youth and Rebellion" are as applicable to society today as they were when the Rebbe Schneerson commented on them decades ago. I ended up buying copies for some friends who are not Jewish.
Rabbi Kalmenson has managed to weave the Rebbe's commentary on various social, psychological, political, and moral issues together with psychological perspectives, that re-enforce and help illuminate the concepts for readers who are more scientifically minded in their approach. In addition, the text is never "dry" due to the interweaving of personal anecdotes from the trove of letters, conversations, and personal stories of both the Rebbe, and those that interacted with him.
I personally found the "Youth and Rebellion" fascinating considering the current "OK Boomer" phase that is making the press currently. By analyzing the underlying causes of generational friction in a society undergoing a paradigm change, the chapter sets perspectives, and potential solutions to our approach, that are quite novel, yet based on a history of this issue recurring again and again. Today's "OK Boomer" was yesterdays "Never trust anyone over 30." so even though the discussions were specifically about generational divide in the 1960s, the fundamental principles and social dynamics are shown to be constant, and that is something Rabbi Kalmenson has done an excellent job in concisely bringing to the forefront of the discussion.
Finally, throughout all the chapters on diverse subjects, the constant that binds the book to it's central, and important theme, is that by understanding the fundamental nature of the problems, and recontextualizing our perceived role within that dynamic, we can improve not only our overall mental health, but the potential outcomes from interaction under times of duress. The authors choice of Rebbe Schneerson's own life helps to put things into perspective.
In the authors own words; "positive perception is applicable and accessible to all. . . it derives from objective, rational insight, not subjective, wishful imagination, and that positive living is a matter of choice, not circumstance."
I know keep a copy with me on my travels, and highly recommend this book to my Jewish and non Jewish friends, or anyone that faces adversity in life, which is really all of us.
