Land-Use Planning and the Question of Unintended Consequences

What I will call the generic theory basically affirms that there often exists a disparity between the intentions of the actors and the outcome of their actions that gives rise to side-effects that are neither expected nor predictable.⁴ Unintended consequences are “incongruent” consequences, because what is in place in this case is a disparity between an action's original purpose and its results (Ermolaeva & Ross, 2011). This occurs because whenever we carry out our intentions in a complex world, there will be countless side-effects that could only partly be foreseen; most of the outcome depends on a series of combined reactions of a largely random nature. In other words, the interplay of forces and circumstances are so numerous and complex that it is impossible to consider all possible outcomes in advance. We can therefore say that any action has immediate effects – to some extent intentional and predictable – along with remote side-effects that are not necessarily intended or predictable. By acting we (intentionally) bring about certain things, while (unintentionally) provoking other things.
