Making Whole-Brain Money Choices

lizard with tounge outIf you want to make good money decisions you are going to need to Tame and Train—tame the lizard and train your left brain. Let me explain.

The cerebrum is literally divided into two sections. The right section, or right brain, lives in the present. It recognizes the moment, taking in all sorts of sensory and anecdotal data. It uses parallel processing to simultaneously process incoming stimuli and see the big picture. Its actions are intuitive, contextual, reflexive, and non-linear. It is easily distracted, loses focus, and is all about the richness of the experience.

The left brain lives in all the time dimensions: past, present, and future. It reflects on connecting the present with the past and future by analyzing data. It uses serial processing to focus and stay on track. Its actions are logical, sequential, and linear.  It is task, goal, and detail oriented which limits its perrspective.

A third area of our brain is the limbic system, the lower or reptilian brain. limbic systemThis controls our emotions and the fight, flight, or freeze responses to a perceived threat. When the limbic brain perceives a threat, it cuts off messages from both the right and left brains, leaving us to respond almost involuntarily. These involuntary responses are based on previous experiences, beliefs, and conditioning. This process helps us react quickly to physical threats like attacks from muggers or mountain lions. The problem is that it also kicks in when we perceive financial threats, so we react according to our previous financial traumas and our ingrained money scripts.

When things are working well with our brain, the right brain recognizes data and sends it to the left brain, which reflects and analyses it and devises a response. Things go awry when, due to fear, stress, or other factors, the left brain is unable to accept messages from the right brain, and visa versa. This leaves the reactive reptilian brain to dominate the response process, and we make our decisions based on fear, hurt, anxiety, or anger. The result is often poor financial decisions.

Sound money decisions are often, but not always, straightforward and unforgiving. Similar to math, they have a high probability of being either “right” or “wrong.” For example, a good money decision would be to commit to saving for retirement and future needs before deciding how much we can afford to spend on clothing, shelter, and lifestyle. This is probably the choice we would make if we fully involved our logical, analytical left brain.

Much of traditional economic theory is based on the assumption that we do make money decisions with our left brains fully engaged. Yet this isn’t how many of us make those decisions. Instead, we often act on impulse or in response to fear, making financial choices emotionally even when they do not serve us well. Researchers tell us that 80% of our responses are made in our right brains.

To make the best financial decisions, we need to “tame the lizard,” or keep our reptilian brain calm in the presence of a perceived financial threat so it does not shut down our cerebrum. Then the right brain can recognize data, the left brain can reflect and analyze the data, and the response is a reasoned one that is in our own best interests.

It is possible to learn how to overcome the involuntary responses of our brains to perceived threats, including financial ones. Next week we’ll discuss some of the ways to do this.

    Good article. I would point out though, that a maxim that I learned from an old, bold financial planner was that the difference between amateurs and professionals is that professionals panic FASTER. I’m not sure it is a truism, of course. I’ve always been slow to panic. Fast panic doesn’t necessarily mean fast action. Also, it doesn’t mean unconsidered action. In fact, it doesn’t require action at all! Just a thought.
