Why not use a very broad research question?

You'll get bored researching it.

You'll find too much information to present.

Broad topics are hard to research.

You can't be persuasive about a broad topic.

Answer 1

Short answer: because a very broad research question makes it hard to do focused, deep, and persuasive research. All four of your statements point to real problems, though some need nuance.

Why a very broad question is problematic
- Unfocused scope: you won’t know what to include or exclude, so your work wanders instead of building a clear argument.
- Too much information: a broad question returns vast, diverse literature; synthesizing it into a coherent piece becomes overwhelming.
- Hard to research deeply: broad topics often require covering many methods, contexts, or disciplines, making rigorous analysis difficult.
- Hard to be persuasive: with too many variables and exceptions, it’s difficult to make a specific, evidence-backed claim.

Notes on your listed points
- “You’ll get bored researching it.” — Subjective but plausible. A vague task is less engaging and more tedious than a clear, solvable question.
- “You’ll find too much information to present.” — True: breadth creates an unmanageable review and forces you to omit important details.
- “Broad topics are hard to research.” — Partly true: they’re easy to find sources for, but hard to synthesize and analyze rigorously.
- “You can’t be persuasive about a broad topic.” — True in practice: convincing arguments require specific claims, evidence, and boundaries.

When a broader question might be OK
- Early-stage exploratory work or a scoping review can use broad questions to map a field. Even then, you should set clear inclusion/exclusion rules and limits (timeframe, geography, population).

How to narrow a broad question (quick tips)
- Specify the population (who), location (where), and timeframe (when).
- Focus the relationship or outcome you’ll examine (what effect, which variable).
- Choose a perspective or method (e.g., economic impact, qualitative experiences, randomized trial).
- Use frameworks: PICOT (health), PICO, or simple “who–what–where–when–why/how.”

Example
- Too broad: “Does social media affect mental health?”
- Narrowed: “How does daily Instagram use affect anxiety levels among U.S. college students aged 18–24 over a semester?”

If you want, tell me your broad question and I’ll help you narrow it into a clear, researchable one.
