How to Master Is It Reasonable
TLDR: Is It Reasonable gives you one short statement about the everyday world and asks whether it makes sense. The skill is not trivia or book knowledge, but common-sense plausibility: does this statement match physical reality, human anatomy, everyday tools, and basic cause and effect? Read each statement literally, identify the key mechanism, and ask if any step violates physical constraints.
Reasonable vs True
A key distinction in this game is that “reasonable” is not identical to “factually verified”:
- The site has two dedicated games for factual truth (Facts and Did You Know).
- Is It Reasonable asks whether a scenario is plausible and sensible in the physical world.
- A surprising claim can still be completely reasonable if the underlying mechanism works.
- The question pool is built in pairs: every reasonable statement has a twin that breaks exactly one detail about it, so each round teaches a distinction rather than raw memorization.
The Core Test: Ask yourself: “Could this happen in real life without violating physics, human biology, or basic cause and effect?” If all components align, it is reasonable. If one essential piece breaks down, it is not.
Progressive Statement Complexity
The question pool spans three distinct complexity depths along the progressive ladder:
- Foundational statements: Clear, everyday situations that can be evaluated immediately (such as drinking water to quench thirst or wearing boots in deep snow).
- Deductive scenarios: Scenarios that require a brief pause to consider scale, time, temperature, or biological limits (such as whether an adult can carry an elephant or if ice stays frozen inside a running oven).
- Subtle mechanisms: Statements that turn on exactly one subtle detail, such as the direction of a process, the specific property a tool measures, or sequence order (such as putting on socks after tying shoes or measuring weight with a thermometer).
The player baseline anchors the starting pool depth. As rounds are won and the level climbs, higher-depth statements are added every seven levels.
Check the Tool and Property: On higher tiers, pay close attention to tools and units. A thermometer measures temperature, not weight. A clock tracks time, not distance. A ruler checks length, not volume. Mismatched tools are a classic signature of unreasonable claims.
Common Traps to Avoid
Watch the sequence order: Many unreasonable statements describe two completely normal actions performed in reverse order. Buying groceries before eating them makes sense. Eating an apple before picking it does not.
Beware of extreme scale: Lifting a bag of flour is reasonable. Lifting a fully loaded freight truck with bare hands is not. Look for exaggerated quantities or impossible human strength.
Look for causal reversals: Wet pavement after rain is reasonable. Rain caused by wet pavement is a breakdown of causality.
