Editing Indicative conditional (section)

==Psychology==
Most behavioral experiments on conditionals in the psychology of reasoning have been carried out with indicative conditionals, causal conditionals,  and [[counterfactual conditionals]]. People readily make the [[modus ponens]] inference, that is,  given ''if A then B'', and given ''A'', they conclude ''B'', but only about half of participants in experiments make the [[modus tollens]] inference, that is,  given ''if A then B'', and given ''not-B'', only about half of participants conclude ''not-A'', the remainder say that nothing follows ([[Jonathan St B. T. Evans|Evans]] ''et al.'', 1993). When participants are given counterfactual conditionals, they make both the modus ponens and the modus tollens inferences ([[Ruth M. J. Byrne|Byrne]], 2005).
