Bias & Blindspot Screener Analysis

Original Fact Check

Claim: Video games cause violent behavior in 90% of teenagers.

Rating: False

Explanation: The cited study actually found correlation, not causation, between gaming and aggressive behaviors in only 15% of participants. The sample size was limited to 100 teenagers and didn't control for other factors. Multiple larger studies have found no causal link between video games and violent behavior.

Refuting Statements Analysis

Evidently False Statements

The sample size is sufficient.
No power analysis, small sample.

Statements Impossible to Verify

All relevant studies have been considered.
No systematic review mentioned.

Refuted Statements
The fact-checker correctly distinguishes correlation from causation.
The fact-checker explicitly states the difference.

Logical Constraint Analysis

CorrelationCausation Fallacy

IF Node_Type(X) = Claim AND SemanticFrame(X, CausalClaim) AND SemanticFrame(find_data_for_claim(X), CorrelationEvidence) THEN IF NOT IsExplicitlyStated(X, 'Correlation does not equal causation') THEN CorrelationCausation = true

The original claim incorrectly infers causation from correlation. The fact-checker correctly identifies this, but the original article remains vulnerable.

Small Sample Size

IF Node_Type(X) = Data AND SemanticFrame(X, Sample) AND SampleSize(X) < 500 THEN IF NOT PowerAnalysisPresent(X) THEN SmallSampleSize = true

The study's sample size (100) is small, raising concerns about generalizability. No power analysis is provided.

Selection Bias

IF Node_Type(X) = Data AND SemanticFrame(X, Sample) THEN IF NOT RandomSampling(X) THEN SelectionBias = true

It is not started if the selection was indeed random, so it gives rise to the possibility of selection bias.
