More precisely: not just having people less intellectually exercised¹, but also and especially creating some sort of "demand" that "things have to be simple". Non-recognition of complexity is also one of the cracks allowing populism. Your duty is to "spend one further thought", while some instances seem to defend an idea of an "as-if-constitutional right to reduced consideration".
