The purchase by Black, Scholes, and Merton of the National General warrants indicates that the theoretical commitments of the financial economists discussed here, strong as they were, did not always take the form of conviction that the field's models were empirically entirely accurate. Some degree of conviction of verisimilitude is perhaps inevitable when a model becomes incorporated centrally into the work of a successful research specialty and researchers have a "shared sense of the group as having achieved a satisfactory, working routine" (Bloor 2004, pp. 24-25).
