    In Tversky’s (1969) model of a lexicographic semiorder, a preference is generated
    via the sequential application of numerical criteria by declaring an alternative x
    better than an alternative y if the first criterion that distinguishes between x and
    y ranks x higher than y by an amount exceeding a fixed threshold. We generalize
    this idea to a fully fledged model of boundedly rational choice. We explore the
    connection with sequential rationalizability of choice (Apesteguia and Ballester
    2010, Manzini and Mariotti 2007) and we provide axiomatic characterizations of
    both models in terms of observable choice data.
