Peterson is virtually always more nuanced than the straw target his detractors have built out of his ideas. He uses the fact that the moods of both lobsters and humans are regulated by serotonin, a neurotransmitter that waxes and wanes in accordance with both creatures’ place in a dominance hierarchy to illustrate the point that the “problem of hierarchy is much deeper” than capitalism or any other set of human institutions. The claim is not that the continuity between our mental architecture and that of much older organisms does or should determine the way we organize society, but rather that it necessarily exerts a degree of influence on it, and constrains the set of viable ways of organizing our society. This modest claim should be self-evident to all but the most insistent denialist. Peterson acknowledges that inequality is a problem in that it causes society to destabilize when it moves past a certain threshold, and acknowledges the necessity of left-wing redistributive political movements — but is wary of left-wing doctrines that call for mandated equality, for the simple and very good reason that the grand experiments in mandated equality of the 20th century tended to be catastrophic. This does not mean that Peterson is a libertarian radical but a moderate conservative. He accepts nearly every facet of the status quo of 2014: he is on video explaining his acceptance of legal abortion, gay marriage, progressive taxation, the welfare state, and the Canadian socialistic healthcare system.
Anyone who listens to Peterson’s actual words without the intent of discovering in them the horrors they already believe that they will find there — i.e., without letting confirmation bias guide them by the nose — will discover that, in fact, his thinking on most discrete problems nearly always bends toward moderation.
