Introduction Examples for the May 2026 Titles

Title 1: Observation as an Essential but Flawed Tool

Prompt: “In the production of knowledge, does it matter that observation is an essential but flawed tool?”

Sample introduction:
“Observation sits at the core of both scientific discovery and artistic expression, yet it is never free from error. While observation enables breakthroughs such as Fleming’s discovery of penicillin, it also produces flawed eyewitness testimony in law. This essay will explore the extent to which flawed observation matters by comparing its role in the Natural Sciences and the Arts.”

See full breakdown in our Title 1 guide.

Title 2: Doubt as Central to Knowledge

Prompt: “To what extent do you agree that doubt is central to the pursuit of knowledge?”

Sample introduction:
“Doubt can act as the spark that ignites inquiry or the barrier that halts progress. In the Natural Sciences, doubt has driven revolutions such as Einstein’s rejection of Newtonian physics, while in History, skepticism of dominant narratives often deepens understanding. This essay will evaluate whether doubt is truly central—or whether it risks undermining knowledge itself.”

Detailed analysis: Title 2 guide.

Title 3: Power of Knowledge Conveyance

Prompt: “Is the power of knowledge determined by the way in which the knowledge is conveyed?”

Sample introduction:
“Knowledge does not exist in isolation—it requires communication to have impact. From the use of propaganda in Nazi Germany to the precision of mathematical notation, the way knowledge is conveyed can amplify or diminish its authority. This essay will explore how far the power of knowledge depends on its mode of communication, focusing on History and Mathematics.”

Title 4: Context in Understanding Knowledge

Prompt: “In the acquisition of knowledge, can we only understand something to the extent that we understand its context?”

Sample introduction:
“Knowledge rarely exists without context. Literature becomes richer when read within its cultural background, and psychological studies require ethical context to be fully understood. Yet some knowledge, such as mathematical truths, seems less dependent on context. This essay will evaluate whether context always determines understanding by comparing Literature and Human Sciences.”

See: Title 4 guide.

Title 5: Pythagoras and “All Things Are Numbers”

Prompt: “To what extent do you agree with the claim that ‘all things are numbers’ (Pythagoras)?”

Sample introduction:
“Pythagoras’ claim that ‘all things are numbers’ raises questions about whether reality can be fully captured through mathematics. From the golden ratio in architecture to the Fibonacci sequence in nature, numbers reveal underlying patterns, but not all experiences can be quantified. This essay will evaluate the extent to which mathematics explains reality by exploring Mathematics and the Arts.”

Title 6: Interpretation as a Tool in Knowledge

Prompt: “To what extent is interpretation a reliable tool in the production of knowledge?”

Sample introduction:
“Interpretation allows us to make sense of evidence, whether analyzing historical documents or explaining quantum mechanics. Yet interpretation is never neutral—it risks distorting meaning and creating bias. This essay will assess the reliability of interpretation by comparing History and the Natural Sciences.”
