A young woman starts to become suspicious of her cellphone. She notices it listing Wi-Fi networks she does not recognize, and the photos on her contact cards seem to mysteriously change at random times. One day she tries to make a call and just hears static on the line. She begins to think that someone – or an entire organization – has hacked her phone or placed spyware in it, and she wonders what crime she is being framed for.
Built-in laptop webcams, unfamiliar Wi-Fi networks, targeted ads on search engines and personalized algorithms on social media sites: Most people have come to accept and ignore the quirks and drawbacks of daily contact with the internet and devices such as cellphones and computers. But for people with severe mental illness, new technologies are fertile ground for the start of false ideas that can lead eventually to a break with reality.
Psychiatrists like me help people who are bothered by their thoughts, behaviors or emotional states. For the past 10 years I’ve been working closely with people who have schizophrenia.
Schizophrenia, sometimes referred to as a type of thought disorder, is a chronic condition in which alterations in brain function change the way one perceives the world. People with schizophrenia can become hyperaware of their surroundings, often interpreting things they see or hear as being hostile and directed toward them even when there’s no real danger.
Over time, people with schizophrenia can develop delusions: beliefs that are fully held even though they are not based in reality and even when there is evidence to the contrary.
With technology and the internet now such an integral part of daily life, it’s no wonder that people with schizophrenia have incorporated new technologies into their delusional beliefs. In my recent research, my colleagues and I set out to explore the ways modern tech influences the content of delusions for people today.
Old delusional themes expressed in new ways
Most delusions are persecutory, meaning a person believes they are being watched, followed or monitored. Other delusional forms involve the belief that a person has special powers, is being controlled by outside forces, or that a spouse is unfaithful even when they are not.
Prior research has shown that these themes are consistent among people with schizophrenia, but the sociopolitical context in which a person lives shapes the form in which they are expressed.
For example, Americans living during World War II developed persecutory delusions involving Germans, while those living during the Cold War focused on communists. People with thought disorders have incorporated important events such as the fall of the Berlin Wall and the O.J. Simpson trial into delusional frameworks.
New technologies offer new raw material for persecutory delusions to work with.
