Even experts give lip service to complexity while relying on simple explanations.

Evidence

The propensity to conserve cognitive resources in seeking and processing information manifests itself in several forms. First, people prefer simple decision rules and unitary causal accounts to ones that posit a multiplicity of factors and causal paths. In areas in which they are expert, people may reject an explanation as too simple, but even here there may be more lip service than actual avoiding of simplicity. — John T.
