Abstract Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic “oughts” that apply in the first instance to belief-forming strategies that are partly under our control. But the beliefforming strategy of not believing conspiracy theories would be a political disaster and the epistemic equivalent of selfmutilation. I discuss several variations of this strategy, interpreting “conspiracy theory” in different ways but conclude that on all these readings, the conventional wisdom is deeply unwise

_Russell on Ethics_ presents a coherent and comprehensive collection of Russell's ethical writings, drawing on a wide range of his publications on ethical concerns, many of which have been difficult to access by students and general readers. Charles Pigden provides an accessible introduction to the papers, situating them within the field of ethics as a whole and detailed annotations on the papers themselves, analysing their arguments and exploring their relevance to current concerns. _Russell on Ethics_ represents a valuable insight into Russell as an ethicist, which will be useful to both specialist and non-specialist alike
