Think you know why people behave a certain way? Dr Kavetha Sun explains how core beliefs can shape our perceptions and make us misread everyday situations.

Ever wondered why the same situation can feel completely different depending on what you believe about yourself and others? In an Instagram post shared on September 21, Harvard-trained, double board-certified psychiatrist and relationship coach Dr Kavetha Sun explained how our core beliefs can quietly shape the way we see everyday situations.

“This is the first thing I teach every patient that walks in through my door,” Dr Sun said. “And if you actually take this to heart and apply it, it will change your life. Here’s the secret: There is no such thing as reality.” (Also read: Rising loneliness among older adults: Psychologist Archana Sharma explains why where you live matters for mental health )

How core beliefs can influence perception

Dr Sun explained that what we perceive as reality can often be influenced by the beliefs we already hold about ourselves and other people.

“Everything that you perceive as reality is actually a reflection of your core beliefs,” she said. “Let’s say you have a core belief that you are hard-working and you cannot tolerate people who are lazy.”

She then used familiar everyday situations to illustrate how such beliefs can influence our interpretation of other people’s actions. “Let’s say your co-worker comes in late to a meeting, or your 9-year-old daughter is dilly-dallying around her math homework, or your spouse said that they would do the dishes and forgot,” Dr Sun said.

We often interpret behaviour through our existing beliefs

“You will immediately see each of these situations and use it to reinforce the belief: ‘See, people are lazy, and I’m hard-working, and I have to do everything around here.’”

However, she pointed out that the behaviour we observe does not necessarily tell us the complete story. “But in truth, we don’t know why that co-worker is late,” she said. “Maybe they’re going through a rough patch in their marriage, or maybe they have to work two jobs to make ends meet.”

The same applies when interpreting a child’s behaviour, she added. “We don’t know what’s happening with your 9-year-old. Maybe she really struggles with math and needs extra help and doesn’t know how to ask for it, and that’s why she’s dilly-dallying.”

Why questioning our assumptions matters

According to Dr Sun, holding firmly to a particular belief can make us less likely to investigate what is actually happening or consider alternative explanations.

“When we have a certain belief, we will not have any curiosity or compassion or further investigation,” she said. “We’ll immediately see this as more evidence of this belief being true.”

Her point is that the same situation can potentially be interpreted in very different ways depending on the beliefs a person brings to it. Pausing before making an assumption can create space to ask questions, consider context and recognise that our first interpretation may not always capture the full picture.
