Ignorance is often a valid excuse for wrongdoing. But authors such as William FitzPatrick argued that ignorance is culpable if we could have reasonably expected the agent to take action that would have corrected or prevented it, given his capabilities and the opportunities provided by the context, but failed to do so due to vices such as laziness, indifference, disdain, etc. Guilty ignorance is still present in the debate and, in recent times, has become more pressing with the problem of (...) technological responsibility. In this paper, an internalist perspective of culpable ignorance is adopted to analyze a form of culpability distribution in the technological context based on dispositional beliefs. Thus, two types of responsibility are found. By examining the implications of culpable ignorance, we realize that we can respond to the unambiguous idea that an engineer is morally and epistemically responsible for certain facts. (shrink)
