In face reading, our physiology or physical structure affects our perception. As an analogy, we might think of how different that the same song sounds when played on a tuba or on a flute. Applied to face reading, one of the ways that we take in information at the inception stage is through our ears. They serve as our antennae. People with really big ears have really good antennae for listening. However, in today's world the majority of our listening time and attention is devoted to primarily listening to words.
Words, like language, are mental constructs which is the province of the left brain. Words are abstracts or symbols that stand for real things, ideas or concepts so that we can capture, evaluate and analyze our experiences. We then project our conclusion into plans for the future or an explanation of the past but the left brain is never in the present moment. People with big ears, in true left brain fashion, like proven methods, trust authority, and reject what is unknown or unfamiliar or what cannot be quickly categorized. These characteristics are all ways that the thinking/analytical left brain processes. It can be very logical but it can also be very literal, hearing the words but missing the implication, tone, or hidden meaning.
On the other hand, a person with small ears has a more right brain approach to listening. They listen more with their eyes than with their ears and they "get it" when they see it. They do well if they take copious notes in class even if they never open up their notebook again. The right brain is visual and it is capturing all of the experiences occurring in the moment.
These small ear people listen to not just the words themselves but also the tone, context, and the total experience including the feeling in the room. They may miss the exact wording but they can catch what was only implied but never said. Because the processing is visual, a small eared person has difficulty listening to a long winded, slow talking, often pausing person who only talks and does not show them anything new. Confronted with that situation, the person with small ears may stop listening and start thinking about something else. This is just one example of how our physiology affects our experience and it is true at every step of the experience.
Once we have taken in the information, we then have to process it for it to make sense or to give it meaning. The forehead and eyebrows are the parts of the face that reflect how we process. For example, round eyebrows reflect a right brain method of processing where there is a preference for real world examples and the opinions of others are valued when making a decision. Straight and angled eyebrows reflect differing degrees of left brain processing. Straight eyebrows are less interested in the opinions of others and prefer to be given the facts or data so they can make up their mind for themselves. While angled eyebrows are even more focused on analyzing and evaluating with a desire to be right and they will almost always have an opinion.
