Answer by Dr. Abbie Maroño, PhD in Psychology & Human Behaviour Analysis, Lancaster University, on Quora:
There is nothing more fascinating to me than human behavior. As a behavioral scientist, I am constantly amazed by the exciting discoveries we make and the vast areas we still have yet to understand. Determining the most intriguing aspects of human behavior is challenging, but two areas stand out to me. These are the role of unconscious processes in our decision-making and the profound impact of our thoughts on our biology.
Lets dig into them both.
Most of Our Decisions and Behaviors Are Unconscious
Research in psychology and neuroscience has shown that a significant portion of our decisions and behaviors are driven by unconscious processes. Indeed, our brains constantly process information below the level of conscious awareness, influencing our choices and actions. This includes automatic responses, habits, and gut feelings that guide our behavior without us actively thinking about them. For instance, if you have ever read Kahneman’s work on “thinking fast and slow” you will know this very well. Kahneman highlights how much of our decision-making relies on fast, intuitive processes rather than slow, deliberate reasoning. This means that many of our daily actions, from what we eat to how we interact with others, are influenced by unconscious cognitive processes shaped by past experiences and learned behaviors.
Let’s take a very simple example we can all likely relate to. Imagine you’re at a grocery store, and without much thought, you reach for a specific brand of cereal. This choice might seem spontaneous, but it’s likely influenced by a variety of unconscious factors: past positive experiences with the brand, its prominent placement on the shelf, or even subtle cues from advertisements you’ve seen. Your brain has processed these influences below the level of conscious awareness, guiding your seemingly automatic decision.
Thoughts Can Change Our Biology
A lot of people underestimate the power of our thoughts, and although it may sound hard to believe, our thoughts can have a profound impact on our biology. One example is the effect of self-talk on stress hormone levels. Studies have shown that negative self-talk can increase cortisol levels, the body’s primary stress hormone, leading to heightened stress and anxiety. Conversely, positive self-talk and affirmations can help reduce cortisol levels, promoting a sense of calm and well-being.
Another compelling example is the placebo effect, where a person experiences a real improvement in their condition after receiving a treatment that has no therapeutic effect. Research has shown that the placebo effect can trigger the release of endorphins, the body’s natural painkillers. For instance, a study using brain imaging techniques demonstrated that patients who received a placebo for pain relief exhibited increased activity in brain areas associated with pain modulation, such as the anterior cingulate cortex and the prefrontal cortex. These changes are similar to those observed when patients take actual pain-relieving drugs. Additionally, the placebo effect has been linked to the activation of the brain’s reward system, which involves the release of dopamine.
These findings provide strong evidence that the belief in treatment can lead to biological changes in the brain, thereby influencing physical health outcomes. The placebo effect not only underscores the power of the mind in healing but also demonstrates the intricate connection between psychological factors and physiological responses.
