Experts Explain Why Negative Thoughts Are Hard to Banish from the Mind

Have you ever considered the worst-case scenario of an event, only for the thought to keep circling in your head even after the situation has changed? A recent psychology study shows that negative thoughts become harder to let go of when they interact with negative emotions and the habit of repeatedly dwelling on problems (rumination).

According to a report by Psychology Today, research led by Lisa M. W. Vos together with Jonas Everaert, Ph.D., from Tilburg University and KU Leuven revealed that people often become trapped in negative interpretations of situations that are actually still ambiguous.

For example, when a text message goes unanswered, a person may initially assume their friend is busy. However, upon seeing that friend active on social media, the assumption arises that they are being avoided. The main problem lies in the inability to revise the initial assumption even when comparative information or a new explanation becomes available.

The study involved 179 adults with varying levels of depression and anxiety symptoms and ran for 14 days. Through monitoring six times a day, the researchers found that participants with high levels of depressive and social anxiety symptoms had the greatest difficulty letting go of negative interpretations.

The researchers identified a strong reciprocal relationship between thoughts and emotions.

“This relationship shows a two-way influence between thoughts and emotions that reinforce one another,” explained Jonas Everaert, Ph.D., Assistant Professor of Clinical Psychology at Tilburg University.

The findings confirm that maintaining mental health does not mean a person must always be forced to think positively. What is far more crucial is building the capacity for cognitive flexibility — that is, the willingness to revisit one’s initial thoughts when new facts emerge.

When a negative thought takes hold, one need not immediately replace it with a positive thought, but simply consider rational alternative explanations.

In addition, emotional management — such as reducing pressure, stopping the habit of rumination, seeking social support, and redirecting attention towards positive experiences — is considered helpful in enabling a person to think more flexibly. Nevertheless, the researchers emphasise that this study is still mapping the relationships between psychological processes and requires further research to test the effectiveness of clinical intervention strategies.
