YES: The majority demonstrates wisdom and insight in making the right decisions in many areas of human interactions.
Majority opinion regarding incompetent government officials or poorly delivered policies is usually right when adequate corroboration of information and news takes place among the masses, particularly in the modern world where data and information is easily accessible, facilitating informed understanding of political matters amongst the public.
In economically straitened times, the majority displays appropriate common sense in their choices as buyers and consumers, prudently spending within their budget for various consumer goods.
In political contests, the majority usually demonstrates wisdom in electing the right candidate to office when it has adequate knowledge about the candidates and their programs as well as a mature voting culture emphasizing informed and rational voting behavior.
In matters relating to art and culture, the majority is usually right about the relative value and appeal of art in its various forms, correctly supporting aesthetically pleasing renditions while shunning those of a more dubious nature or delivery.
NO: The majority is prone to error and poor judgment in many human activities and moments requiring effective decision-making.
Even with access to information, the public may form hasty or poor judgments about government policies as the majority view may be driven by emotions rather rationality, and feature correspondingly short-sighted views rather than deep solutions towards important societal issues.
Consumer decisions are often influenced by trends and trend-setters, such as celebrity endorsements, which shape majority views on what are the most desirable goods and products, leaving room for many dubious buying choices whatever the economic circumstances.
More often than not, the many conditions for effective voting are absent in many political contests, and the majority elects leaders based on the emotional appeal of populist programs or other unrealizable campaign promises that charismatic candidates put up.
Art and culture is always subjective and difficult to value accurately, making the majority view highly suspect as our collective aesthetic sensibilities about what is good or bad art are often undermined by external influences, such as music popularity charts or self-interested valuations by art auction houses.
