The four arguments presented below all contain a flaw in causal reasoning based on an observed correlation. Pair each argument with the statement that most accurately describes its specific logical vulnerability.
- An agricultural survey shows that farms utilizing heavy-duty automated irrigation systems experience significantly higher crop damage from pests than farms using manual watering. The report concludes that the automated machinery must be attracting insects.Fails to consider that an underlying third variable might be independently responsible for both observed phenomena.
- Biologists observed that a certain species of tree frog exhibits exceptionally bright skin coloration during seasons with high mosquito populations. They hypothesize that the bright coloration is causing mosquitoes to swarm the frogs' habitat.Overlooks the possibility that the actual direction of causation is the reverse of what the argument concludes.
- Over the last fifteen years, the global population of a rare migratory bird has declined at roughly the same rate as the increase in residential solar panels installed worldwide. A wildlife advocate argues that solar panels are interfering with the birds' navigation.Unjustifiably interprets a coincidental statistical alignment between two independent trends as evidence of a causal link.
- A physical therapy clinic's data indicates that patients who frequently use the clinic's specialized back braces report more intense lower back pain than patients who do not use them. The clinic's director concludes that the back braces are exacerbating patients' pain.Ignores the possibility that individuals adopt a specific behavior precisely to mitigate a pre-existing condition.
Cevap
Farm automation matches with the third variable flaw; frog coloration matches with reverse causation; solar panels and bird decline matches with coincidental trends; and back braces match with mitigating a pre-existing condition.
Each argument commits a specific variation of the correlation-causation fallacy. The agricultural argument overlooks an external third variable. The frog argument reverses the likely biological cause and effect. The bird argument forces a link between independent timelines. The back brace argument confuses a treatment for a condition with the cause of that condition.
