The Duality of the Mind: The Interaction between Emotion and Reason in System 1 and System 2 Thinking

The human brain is one of the most complex and mysterious organs in the body. Despite centuries of scientific research and advancements in technology, we still have much to learn about how it functions. One of the challenges in understanding the brain is the identification of specific neural correlates or substrates of certain functions. In other words, understanding which specific regions of the brain are responsible for specific cognitive processes.

One of the key distinctions in cognitive science is the distinction between System 1 and System 2 thinking. System 1, also referred to as the experiential system, is characterized as effortless, automatic, and fast. It is responsible for quick, emotional reactions and can lead to errors. This mode of thinking is often referred to as intuition, and it performs the quick acts of prowess that became popular under the name “blink” after the title of Malcolm Gladwell’s bestselling book. System 1 is highly emotional, precisely because it is quick. It produces shortcuts, called “heuristics,” that allow us to function rapidly and effectively.

On the other hand, System 2, also referred to as the cognitive system, is characterized as effortful, reasoned, and self-aware. It is responsible for more deliberate, conscious thinking and makes fewer errors than System 1. This mode of thinking is what we normally refer to as “thinking”. It is what you use in a classroom, as it is effortful, reasoned, slow, logical, serial, progressive, and self-aware (you can follow the steps in your reasoning).

One of the key distinctions between these two systems is that while System 1 operates automatically and unconsciously, System 2 operates deliberately and consciously. This is important to note because most of our mistakes in reasoning come from using System 1 when we are in fact thinking that we are using System 2. This is because System 1 operates quickly, without thinking and introspection, and thus, our lack of awareness of using it is its main property. System 1 is also highly prone to cognitive biases, which often lead to incorrect decisions. Since System 1 is a reflexive and instinctive process, it is heavily influenced by our beliefs and values, which can lead to inaccurate assumptions and judgments. Thus, it is important to recognize when we are relying on System 1 and to be aware of our cognitive biases so that we can correct them and make better decisions in the future.

One of the best examples of how our observations keep evolving and how they change our perception of the relationship between the size of the brain and intelligence is the study of animals such as bats and parrots. For example, researchers have observed that bats use a combination of vision and echolocation to navigate and locate prey, while parrots have been found to have advanced cognitive abilities and can even understand basic concepts of number and physics. These examples illustrate the importance of relying on observation rather than simply studying neural correlates.

Bats, for instance, have a unique visual system that allows them to see a wider range of colors than humans and many other animals. They also have a higher resolution and can detect much finer details than humans. However, not all bats rely solely on vision, some bats hunt during the day, such as the vampire bat, have good eyesight and rely on both vision and echolocation to catch their prey, while bats that hunt at night, such as the little brown bat, rely primarily on echolocation. This observation shows that the visual acuity of bats varies depending on the species, some bats have better eyesight than others, and that different species have different hunting strategies, thus, it is important to observe their behavior in their natural environment.

Similarly, parrots have also been found to have advanced cognitive abilities, they have been observed to understand basic concepts of number and physics, they can mimic human speech, and can understand and use human words, which is a cognitive process previously thought to be unique to humans. These observations indicate that parrots have complex cognitive abilities that are not fully understood yet.

These findings have important implications for further understanding how the brain really works. They highlight the need for a holistic approach to studying the brain, one that takes into account not only neural correlates but also observation of behavior in natural environments. Additionally, these findings challenge the traditional belief that a larger brain equates to higher intelligence, as both bats and parrots have smaller brains than humans but possess advanced cognitive abilities.

Furthermore, these findings also highlight the importance of using the empirical method in parallel to studying neural correlates. The empirical method allows for the collection of data through observation and experimentation, and it is essential in understanding the complexities of the brain. It also allows for the development of hypotheses and theories that can be tested and refined over time.
