In popular discourse, "populism" is sometimes used in a negative sense in reference to politics which involves promoting extremely simple solutions to complex problems in a highly emotional manner. Mudde suggested that this definition "seems to have instinctive value" but was difficult to employ empirically because almost all political groups engage in sloganeering and because it can be difficult to differentiate an argument made emotionally from one made rationally. Mudde thought that this phenomenon was better termed "demagogy" rather than "populism". Another use of the term in popular discourse is to describe opportunistic policies designed to quickly please voters rather than deciding a more rational course of action. Examples of this would include a governing political party lowering taxes before an election or promising to provide things to the electorate which the state cannot afford to pay for. Mudde suggested that this phenomenon is better described as "opportunism" rather than "populism".
