Lying by Promising

What is it about?

A statement is a lie if it is believed to be false. But what about promises and other 'speech acts', like questions, requests and declarations? This study analyses the conditions under which a promise can be a lie. It introduces a distinction between insincere intentions (you don't intend to do what you promised) and insincere beliefs (you don't believe you will do what you promised). The relevance of this distinction is then tested with a survey, showing that English speakers call a lie any promise accompanied by either insincere intentions, or insincere beliefs, or both.
