(bright music) (cymbals crashing) Primatologist Frans de Waal and others have argued that empathy is a fundamental human trait, as it was born out of our evolutionary journey into becoming Homo sapiens. He argues that empathy is a necessary characteristic of members of human society. Empathy is also considered by scientists and experts to be one of the key factors to functioning properly in human society due to the way empathy compels people to take actions that benefit others, also known as prosocial behaviors. In many interpersonal communications, empathy can help foster understanding by getting at not only what someone is saying but why they're saying it. According to "Psychology Today," empathy is the capacity to be aware of others' emotions and to understand what someone else might be going through mentally and emotionally. A person exhibiting empathy may also be able to understand others' emotional responses, even if they don't feel the same emotions themselves. You might express deep empathy for others if you have a keen awareness of how someone might be feeling, have a good sense of when people are lying, are often mentally preoccupied with the suffering of others, are able to feel other people's pains by imagining yourself in their position, or are emotionally affected by severely negative events even when you share no personal connection to those affected. Even if you aren't sure you're empathetic, others might have picked up on your empathetic tendencies. In these cases, other people might feel compelled to discuss their personal issues with you, ask you for advice, or ask you for other kinds of help. Possessing deep reserves of empathy has both its advantages and disadvantages. On one hand, you are better able to understand and even feel other people's joys and pains. This can make you feel closer to people and better able to navigate conversations and work relationships. On the other hand, empathy can also make you more vulnerable to becoming preoccupied, worried by, or emotionally affected by others' suffering. This can be exhausting, both mentally and emotionally. You may also find yourself more concerned with others' wellbeing than with your own, putting more effort into doing things for other people while neglecting your own personal priorities. In certain cases, you might even act in ways that go against your own reasonable interests. For example, showing up late to work because you helped a lost stranger find their destination. Being empathetic does not always mean you will emotionally experience what another person is feeling. Certain kinds of empathy are more mental than emotional. People exhibiting such responses will often be able to recognize what the other person is going through emotionally or mentally but won't necessarily feel it themselves or experience the adverse effects that often accompany strong emotional reactions.
