Giving algorithms a sense of uncertainty could make them more ethical

The algorithm could handle this uncertainty by computing multiple solutions and then giving humans a menu of options with their associated trade-offs. Say the AI system was meant to help make medical decisions. Instead of recommending one treatment over another, it could present three possible options: one for maximizing patient life span, another for minimizing patient suffering, and a third for minimizing cost. “Have the system be explicitly unsure and hand the dilemma back to the humans.”

I think about clinical reasoning like this; it’s what we call the kind of probabilistic thinking where we take a bunch of – sometimes contradictory – data and try to make a decision that can have varying levels of confidence. For example, “If A, then probably D. But if A and B, then unlikely to be D. If C, then definitely not D”. Algorithms (and novice clinicians) are quite poor at this kind of reasoning, which is why they’ve traditionally not been used for clinical decision-making and ethical reasoning (and why novice clinicians tend not to handle clinical uncertainty very well). But if it turns out that machine learning algorithms are able to manage conditions of uncertainty and provide a range of options that humans can act on, given a wide variety of preferences and contexts, it may be that machines will be one step closer to doing our reasoning for us.

    • In times of change, learners inherit the earth, while the learned find themselves beautifully equipped to deal with a world that no longer exists
    • How our children learn is critical today, not so much as a point of pedagogy, but for the development of a distinct and most important skill – learning
    • The job of education should be to wean children from the teaching, helping them to become, at graduation, independent, skilled, inspired, and responsible learners eager to adopt and adapt to changing conditions, turning uncertainty into opportunity
    • Being future ready will not happen because of the rigor of ramped up standards.  It will happen by scaling back the standards as the education years pass, focusing on passion, and providing students with the support, opportunity and facility to learn and to make themselves experts in their shifting fields of interest, fields that educators skillfully usher them through
