In their words
Positions and remarks grouped by topic, each with the exact quote and where it was said.
Self-improvement
Greenberg argues the least sexy but highest-impact strategy is actually putting techniques into practice.
“many people read self-improvement books and they do nothing differently afterwards. It will not change your life until you actually put it into action”

Greenberg says his biggest takeaway from running over a hundred psychology studies is that humans differ far more than they realize.
“my biggest takeaway about human nature is that we humans are way more different from each other than we realize”

Greenberg argues that people are disillusioned with self-help because they are promised a silver bullet, whereas even the best methods are contextual.
“the reality is there isn't one silver bullet that works for all people at all times”

Overthinking and worry
Greenberg doubts that intelligence is strongly linked to worry, though it may relate to overthinking.
“I know there's a perception that they are, but I don't think it's actually very linked to worry per se. Overthinking probably more so”

Greenberg recommends scheduled worry time, which shows anxious people they have more control over worry than they believed.
“people start to realize, huh, I seem to have more control over my worry than I thought”

Exposure therapy
Greenberg recounts that a fear-hierarchy program over about six months dramatically reduced his lifelong social anxiety.
“my social anxiety fell dramatically. And I certainly still have social anxiety sometimes today. But it's shockingly less than it was”

Greenberg says exposure therapy requires avoiding safety behaviors, which teach the brain the wrong rule.
“you have to avoid engaging in safety behaviors. So safety behaviors are things we do to make ourselves feel better in those situations, but they cause our brain to learn the wrong rule”

Habit formation
Greenberg says habit reflection, applying lessons from a past successful habit, was the standout technique in his study because it is self-adapting.
“the most effective technique we found, the most promising one in our study, was one that we call habit reflection”

Behavioral activation
Greenberg says behavioral activation shows that scheduling enjoyable activities can generate positive thoughts in depressed people.
“just getting them to do more positive activities that they really enjoy actually tends to produce more positive thoughts”

Ego depletion
Greenberg says scientific understanding of willpower as a depletable muscle collapsed when ego depletion findings failed to replicate.
“researchers tried to replicate it and did not replicate. They could not replicate a bunch of the basic findings”

Productivity

“productivity equals time, times efficiency, times importance”

Internal family systems
Greenberg says schema therapy, which also uses parts work, has more evidence of efficacy than internal family systems.
“I believe it's used in schema therapy, which actually has surprisingly more evidence for its efficacy than internal family systems”

Intrinsic values
Greenberg says his research identified 22 categories of intrinsic human values.

Cold exposure
Greenberg says the evidence for long-term health benefits of cold exposure is weaker than commonly assumed, despite reported short-term alertness.
“the evidence base for having long-term health benefits is actually much weaker than you might think”

12 Levers (book)
Greenberg says that after cataloguing techniques from over 100 self-help books and 20 therapies, they could be reduced to 12 psychological levers.
“much to our surprise, we were able to boil it down to just 12 levers, which is these 12 underlying psychological strategies”
