Rick Hanson on the Three Needs: Safety, Satisfaction, and Connection

In this part of the conversation, Erik checks in with Dr. Rick Hanson about time. There's room on both sides to keep going, and Hanson says he can stay on until roughly ten minutes past the hour. One small correction comes first: Erik refers to "four needs," and Hanson gently points out that he actually works with three. Safety, satisfaction, and connection.

Hanson explains that one way to put the science of positive neuroplasticity to work is to target specific issues in specific people. The map he leans on comes straight from how the brain developed. He sorts it into three evolutionary layers: reptilian, mammalian, and primate (or human).

Over something like 600 million years, the brain assembled itself in stages. First came the reptilian brain stem. Resting on top of that are the mammalian subcortical structures, the basal ganglia, hippocampus, amygdala, thalamus, and hypothalamus among them. And layered over all of that sits the primate and distinctly human cortex.

Each of those three stages, Hanson says, came with a growing ability to handle three basic needs that any animal has, broadly speaking: safety, satisfaction, and connection. The specifics obviously differ wildly from creature to creature. A lizard looking after its need for connection is doing something very unlike a human teenager fretting over connection the night before a big school dance. Still, all three needs are woven into animal life itself.

The needs line up loosely with the brain's layers. Safety is anchored deep in the reptilian brain stem. Satisfaction, and the ways we chase after it, gets its shape from the mammalian subcortical regions. Connection, the whole social side of being alive, runs mostly through the cortex. In practice, Hanson boils the work of meeting these needs down to three movements: avoiding harms, approaching rewards, and attaching to others.

That gives a tidy framework to hold onto: safety, satisfaction, connection, or in shorthand, lizard, mouse, and monkey. Some people carry particular safety needs, and for them certain experiences do the targeting. Relaxing. Sensing inner strength. Feeling protected. Noticing that, right now, you are actually okay. Hanson describes cutting through what he calls "paper tiger" paranoia, the habit of blowing up the size of a threat while shrinking our sense of what we can bring to meet it.
