The Rise of the Armchair Psychologist: Weighing the Risks and Rewards of Self-Diagnosis

Strategic Insights -

In an era of social media therapists, online personality tests, and YouTube gurus, self-diagnosis has become increasingly popular. However, this trend carries both risks and rewards. Clinical psychologist Professor Jill Newby explains that while the internet's accessibility and ease of use can be beneficial, the accuracy and qualifications of the information can be a major concern. She warns that algorithms and the way information is presented online can be alarming and prioritise popularity over suitability.

Key Takeaways:

  • The internet and social media have made it easier for people to access mental health information, but the accuracy and qualifications of this information are a major concern.
  • Self-diagnosis can be the first step toward seeking real help, but it can also delay diagnosis, lead people to pursue the wrong types of treatment, or result in incorrect self-diagnosis.
  • Clinical terms such as "trauma," "anxiety," and "depression" are being used in everyday language, which can blur the line between normal experiences and diagnosable disorders.
  • Using these terms loosely can pathologise ordinary stresses and setbacks, and may reduce the meaning of what is considered a trauma.
  • People are misusing diagnoses to describe others, particularly in conflicts, which can reinforce prejudices and dilute the meaning of serious disorders.
  • The internet has also opened up access to reliable, evidence-based information, and self-diagnosis can be the first step toward seeking real help.
  • Our need for certainty can drive us to self-diagnosis, and familiarising ourselves with psychological concepts can even destigmatise conditions.
  • The real challenge is in keeping the benefits of self-diagnosis, such as openness, awareness, and access, without losing sight of the expertise that makes diagnoses meaningful.
