that's a flippant guess. the underlying reasons or the reasoning for others' decisions may not be apparent to you (i.e., under-explained).
beyond that, if decisions others make often seem not reasonable, it's probable that you disagree with the values on which those decisions are based, rather than those business decisions being without reason. you may be entirely justified in your disagreement, but that's a different animal from unreasonableness.
also, most business decisions are made under uncertainty and with imperfect information (under-informed), and many can seem less reasonable in hindsight as a result.
in any case, it's really unlikely that decision makers are chaos monkeys even if it seems that way from your vantage point.
