JAKARTA - Do you often forget things in everyday life? This condition is actually natural and can even be a sign of intelligence from someone.
This was revealed through a study conducted by researchers Richard Frankland and Blake Richards from the University of Toronto. They say that the memory function is not to store information accurately at all times.
In contrast, memory serves to make smart decisions and maintain important things, and ignore various irrelevant things.
"It is important for the brain to forget irrelevant details and focus on things that want to help make decisions in the real world," said Richards, quoted from IFL Science, on Monday, September 22, 2025.

According to a study conducted, continuous changes between old and new memories have real evolutionary benefits. This can help a person adapt to a new situation by releasing old information that is no longer important and can be misleading.
Thus, the brain helps forget specific things about past events while still containing an overview. This can make a person able to generalize previous experiences and apply them better for the current situation.
"And when we see what it takes to make smart decisions, we argue that forgetting some things is healthy," he added.
In addition, in today's modern times, the brain does not need to store information such as phone numbers or other facts that are easy to find in search engines. The brain is better used to store important memories.
"Instead of storing irrelevant information that our phones can keep, our brains are freed to keep memories that are really important to us," Richards concluded.
