To form a fully honest opinion, I would have to research the research and then compare it to additional, similar, and subsequent research....
That said, from the Poly-Sci (Political Science) world, it is said that every movement has its passionate element. Of course, the poly-sci world borrows from many different disciplines including psychology, sociology, history, organizational dynamics institutional dynamics, and more; they may beg to differ but.... Sometimes the passionate element of a movement can become zealots. - You are probably too young to remember the "bra burners"; these were folks from the women's movement of the 1960's who actually burned their bras in protest of the women's position in society. Long before gangster rap, preachers had record (vinyls) breaking parties of all things Motown, Rock-n-Roll, Elvis Presley, and more. Fahrenheit 451 is a Ray Bradbury novel centered around the burning of unapproved books. One of the reasons why we treat religion, politics and leash laws gingerly around the casual conversation table is that many have passionate to zealous feelings and opinions about these topics.
Most of us have been exposed to the business management world (which some say is simply the poly-sci world in a smaller pond) and "change". From this world, we are/were taught that: "Change occurs when the perceived benefits outweigh the perceived pains of the status-quo and the effort to change." From multiple worlds, including our own gut, it is said that: "Fear is a powerful motivator." (The business world does also say that "You change what you reward". Those with a little more depth will also say: "Be careful about what you are actually rewarding as opposed to what you intended to reward."). From the world of psychology, we are/were taught that: "Fear elicits a fight or flight response." Also, from psychology we are/were taught that: "Fear is the base emotion of anger."
So, does the report you cite shock me? - No - It does raise a curiosity in me however with the "more likely to cheat and steal". I'm curious as to what criteria was used to arrive at these conclusions. It seems as if the violins sing at least a little on every budget and funding request I've seen on and off the job. More than a few of us look for every loop hole, gray area/rule, and creative interpretation when doing our taxes, entering a contest, establishing an accounting system, applying for a building permit, and more. Speaking of which, how many report our garage sales earnings or the value of "bartered labor" between neighbors and family members on our state and federal taxes; how about those few dollars of unreported cash that exchange hands else wise? Are "green consumers" cheating/fudging when they consider carbon credits in their daily lives; or are we talking of the recording of carbon exchange efforts of commerce, as opposed to having an eye on sustainability of which carbon credits are but one measure? Are "green consumers" stealing when they dumpster dive, or simply pick something up along side the rubbish bin in the alley? - There are plenty of folks outside, as well as within, the green movement who would have to be taught the moral decadence of this one. And even then, many would not consider this type of activity to be morally decadent; they may come to know and understand the illegality of it, the moral rational of not doing it/doing it in some cases, but probably not undergo an internal transformation of personal moral code revolving around the picking up and using of others' refuse.
