Psychological solipsism

Psychological solipsism is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Psychological solipsism rather than just read about it. In short: Psychological solipsism or solipsism syndrome is a psychological state in which a person feels detached from external reality and perceives the world as existing only within their own mind. Extended periods of social isolation and confinement may contribute to the development of this condition.

Key takeaways

Psychological solipsism belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Psychological solipsism to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Psychological solipsism from memory before moving on to harder problems.

Reference excerpt

Psychological solipsism or solipsism syndrome is a psychological state in which a person feels detached from external reality and perceives the world as existing only within their own mind. Extended periods of social isolation and confinement may contribute to the development of this condition. In particular, the syndrome has been identified as a potential concern for individuals living in space for extended periods of time.

Overview The philosophical definition of solipsism is the idea that only one's mind is sure to exist. In a solipsistic position, a person only believes their mind or self is sure to exist. This is part of self-existence theory or the view of the self. Individuals experiencing solipsism syndrome feel reality is not 'real' in the sense of being external to their own minds. The syndrome is characterized by feelings of loneliness, detachment and indifference to the outside world. Solipsism syndrome is not currently recognized as a psychiatric disorder by the American Psychiatric Association, though it shares similarities with depersonalization-derealization disorder, which is recognized. Solipsism syndrome is distinct from solipsism, which is a philosophical position that nothing exists or can be known to exist outside of one's own mind rather than a psychological state. Advocates of this philosophy do not necessarily suffer from solipsism syndrome, and sufferers do not necessarily subscribe to solipsism as a school of intellectual thought. Periods of extended isolation may predispose people to solipsism syndrome. In particular, the syndrome has been identified as a potential challenge for astronauts and cosmonauts on long-term missions, and these concerns influence the design of artificial habitats.

Worked examples

Example 1 — a first encounter with Psychological solipsism

Start with the simplest possible case. Write down what Psychological solipsism claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Psychological solipsism before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Psychological solipsism ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Psychological solipsism

In research: Psychological solipsism appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Psychological solipsism in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Psychological solipsism is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mental states, Psychopathological syndromes, Solipsism, so understanding it makes those chapters shorter.
In everyday life: Look for Psychological solipsism outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
