IB Theory of Knowledge 2.12.15 IA Prompt 15: What Constraints Are There on the Pursuit of Knowledge? Notes

2.12.15 IA prompt 15: What constraints are there on the pursuit of knowledge?

What the prompt asks

1. Use the prompt exactly as your title: What constraints are there on the pursuit of knowledge? Show how the constraints you identify affect particular inquiries.
2. Because it asks what constraints there are, the lazy route is a list, and a list of kinds of constraint is description with three photographs attached. The work is in showing a constraint operating on one inquiry.
3. Pursuit points at the activity, not the finished knowledge. So look for objects that sit on the process: the permission that had to be sought, the instrument that set the floor, the money that ran out, the question struck off a form.
4. Constraints worth separating: what can be detected, what can be funded, what is permitted, what ought not to be done, what can be asked out loud, and what our concepts and languages are able to hold.
5. A constraint can still shape an inquiry when researchers find a way around it. Explain whether it stopped the work, redirected it or added demands the researchers had to meet.
6. Another prompt on the list asks whether some knowledge ought not to be sought at all. That one is a question about what is permissible; yours is about what bears on the pursuit, so ethics belongs here as one constraint among several.

A real constraint changes the inquiry: what could not be observed, asked or published

1. One useful test is to ask how an inquiry would have run differently without a proposed constraint. Support that comparison with evidence of what the researchers could attempt.
2. That test commits you to a counterfactual, so keep the counterfactual small. What the inquiry would have produced is unknowable in detail; what it was set up to attempt is often written down in a proposal, a protocol or a method section.
3. Constraints can affect observation, the questions researchers ask, and publication. A signal below a method's detection limit, an item removed from a survey and a withheld finding show different points at which inquiry can be limited.
4. A constraint on publication may leave a dated record of a decision. Where that record exists, it can help establish who restricted access and why.
5. A stated detection limit can help explain what a method could reliably detect. A result below that limit does not establish that the substance is absent, or that nothing can be inferred about its concentration.
6. Some objects state a limit directly; others need supporting sources to explain it. In either case, show how the evidence connects the limit to this inquiry.

Constraints protect as well as obstruct, and one object can show both at once

1. Ask what a constraint was intended to protect. A consent requirement can limit recruitment while protecting people's choice about whether to participate.
2. One document can show both a restriction and a protection. Explain how these functions interact in its real-world context.
3. Self-imposed constraints raise a further question: why would researchers limit an inquiry they wanted to pursue? A published call for a moratorium can supply evidence of their stated reasons.
4. Voluntary participation protects choice, but it does not guarantee accurate answers or a representative sample. Consider separately what a consent rule protects and how it affects the evidence researchers can collect.
5. A protective rule may also be challenged as conditions change. To argue that it has outlasted its purpose, you need evidence about the current risk as well as the rule's original reason.
6. Weigh the effects the evidence supports. You may conclude that a constraint both protects participants and narrows an inquiry without deciding that one effect cancels the other.

Object bank

1. The consent or ethics form your school issues for projects involving people, for a stated year. Its context is your school, the committee or teacher who approves it, and whichever projects it has held up.
2. A water-quality or air-quality report published by your local authority, at the line that reports a substance as below the limit of detection. Its context is the sampling date, the laboratory and the method that set that floor.
3. A document released with passages blacked out, from a public information request, cited by agency, request reference and release date. The blackouts and the exemption codes beside them are the object.
4. A declined application for funding, a grant or a competition entry belonging to you or your club, with the date and the reason given. Its context is the funder, the project that stopped, and what the money was for.
5. A copy of the summary statement issued after the Asilomar conference on recombinant DNA molecules in 1975. It recommended safeguards for much of the work and deferral of specified experiments that available containment could not support safely. Identify the publication and passage you use.
6. A dated capture of a website's terms of use restricting automated collection, or its robots.txt file requesting limits on crawling. These are different kinds of constraint: robots.txt is not itself access authorisation or a technical barrier. Explain how the rule affected a particular inquiry.

Locked does not mean unknown: restricted access is not absent knowledge

1. Two different things get called constraints, and separating them is most of the work in this section: knowledge that was never produced, and knowledge that was produced and then held back.
2. A blacked-out passage shows that material has been withheld. It does not establish that the hidden statement is true or that it contains knowledge rather than an allegation, an error or personal information.
3. A restriction on circulation can constrain later inquiry by limiting access to evidence. Check whether the next inquirer had other ways to obtain or test the information.
4. For a redacted document, identify what the requester sought, what the agency withheld and how that affected the inquiry. Avoid assuming that the agency was the only holder of the information or that the inquiry stopped entirely.
5. Knowledge can also be public and unrestricted but hard to locate. An archive without an index may slow inquiry even though researchers are permitted to consult its contents.
6. Distinguish a limit on producing knowledge from a limit on access or discovery. A locked record alone cannot establish which of these applies.

Linking objects to the prompt: examples for analysis

1. Trace what somebody was trying to find out, which condition affected the inquiry and what evidence shows its effect. This is a planning method, not a required sentence structure.
2. On the water-quality report: the method limits how reliably a low concentration can be detected. The printed limit helps explain why a non-detection does not establish absence. What can the reported result support, and what remains uncertain?
3. On the released document: an exemption code can identify the agency's stated basis for withholding passages. Read the cited exemption before claiming what the redaction protected or prevented.
4. On the Asilomar statement: researchers recommended deferring specified recombinant DNA experiments given the containment capabilities then available. The statement supports a claim about recommended limits; evidence of implementation is needed to show what happened in a particular laboratory.
5. Note the limit of that last one. The statement records what was recommended, so a commentary claiming that every laboratory complied has gone past the object, and the smaller claim is the one worth writing.
6. Check what each object contributes. Three technical limits can support different points about inquiry; three repetitions of the same point will not explain why each object belongs in the exhibition.

Failure modes on this prompt

1. The first failure is naming difficulty without explaining the constraint. An experiment needing three attempts may reveal a limit of time, equipment or method; identify it rather than assuming that repeated attempts prove or disprove a constraint.
2. The second is the unsupported counterfactual, and it has a tell: the words would have. Search your commentary for them, and check each one against something written down at the time rather than against what seems likely now.
3. The third is letting an ethical verdict replace analysis of the constraint. Ethical objections can belong here, but explain how they affected what researchers could pursue.
4. The fourth is the drift into suspicion, and you can catch it by size: the less an object shows, the larger the claim being made about it. Where your boldest sentence sits under your least informative object, the argument is running on what is missing.
5. The fifth is the symbolic object: a padlock, a fence, a no-entry sign, chosen because it looks like the topic. A photograph of a padlock records a lock and no inquiry, so the commentary has to supply everything.
