The Optional Themes
Where does knowledge matter most?
Where does knowledge matter most?
The core theme asked how we know what we know. The optional themes ask a different question: what happens when that knowledge is put to use?
This part of the course takes the ideas you have already developed - about evidence, perspective, justification, and responsibility - and places them into contexts where the stakes are real. These are not new subjects to learn. They are situations in which knowledge is produced, contested, and applied. The aim is not to move on from the core theme, but to test it. The same questions remain. What changes is where they are asked, and what follows from the answers.
The IB expects you to study two of the following five themes:

The IB expects you to study two of the following five themes:
|
Knowledge and Language examines the medium through which most knowledge is expressed. Language does not simply communicate ideas; it shapes them. What can be known if it cannot be said? How does meaning shift across contexts, cultures, and translations? And how far does clarity depend on the limits of language itself? |
Knowledge and technology asks how tools shape what and how we know. Technologies extend human cognition, but they also structure it: what gets measured, what gets ignored, and what counts as reliable knowledge. When decisions are made by algorithms, the question is no longer just what is true, but whose knowledge has been built into the system. |
|
Knowledge and Politics
Knowledge and Politics explores the relationship between knowledge and power. Political life depends on claims about truth, but it also determines which claims are heard, trusted, or dismissed. When does disagreement become misinformation? And who gets to decide what counts as knowledge in the first place? |
Knowledge and Religion
Knowledge and Religion considers forms of knowledge grounded in faith, authority, and tradition. These claims often operate by different standards from empirical or scientific knowledge. The question is not simply whether they are true, but how they function as knowledge within communities, and how they interact with other ways of knowing. |
|
Knowledge and Indigenous Societies
Knowledge and Indigenous Societies challenges the assumption that knowledge is universal. Different communities develop distinct systems of knowledge, often rooted in place, tradition, and lived experience. What happens when these systems meet dominant global frameworks? And what is lost when one form of knowledge is treated as the standard for all others? |
Across all five themes, the same underlying issue returns: knowledge does not exist in isolation. It is shaped by the systems in which it operates. The core theme gave you the tools to examine knowledge. The optional themes show you why those tools matter. By the end of this section, the task is not just to ask how do we know? but to recognise, in any situation: what is shaping the knowledge here — and what follows from that?
