The halo effect and social media: how appearances influence our perceptions
What is the halo effect?
The halo effect is a cognitive bias described by the psychologist Edward Thorndike in 1920. It consists in the fact that a single positive characteristic - such as physical appearance or charisma - influences how we value a person in general.
For example, if we find someone attractive or likeable, we tend to believe that they are also intelligent, successful or trustworthy... even if we have no proof of this.
This effect occurs in the form of automatic, fast and almost unnoticed.
How does the halo effect work in social networks?
On platforms such as Instagram, TikTok or YouTube, the halo effect is amplified. The first visual impression strongly influences our perception:
Common examples
-
An account with professional aesthetics, good photos and polished language may appear more “expert” or trustworthy, even if we don't know their background.
-
Influencers who show only a selected part of their life generate the feeling that “everything in their life is perfect”.
-
We follow health or wellness advice without checking the training of the person giving it.
⚠️ This can influence how we feel, what we buy and who we give our attention to.
Why is this bias important to know?
Knowing the halo effect is key to:
-
Taking care of your mental healthComparing yourself to seemingly perfect lives can lead to anxiety, low self-esteem or dissatisfaction.
-
Avoiding misinformationYou can give credibility to untrained people, especially on sensitive issues such as mental health, nutrition or psychology.
-
Protecting your relationshipsYou may idealise people you only know through networks, generating unrealistic expectations.
How to avoid falling into the halo effect?
Here are some guidelines to help you navigate the networks with more awareness:
-
Question what you seeWhat evidence is there to support this claim?
-
Remember that the networks show only a partThey are an edited showcase, not the whole reality.
-
Distinguishes form and content: A beautiful aesthetic does not always imply quality or professionalism.
-
Strengthen your self-esteemNo one's life is perfect. Compare yourself to yourself, not to images.
