Don't give me any more facts! Justify this Decision
Theory of Knowledge Paper for TOK Class
'Don't give me any more facts! I need to make a decision right now!' Although one can question knowledge endlessly, one cannot forever suspend judgement while researching and reflecting. What would it mean to act responsibly in a situation where one cannot possess certainty? How would one justify the decision?
The question of decisions which must be made without the support of a full array of facts is an interesting one. Such a decision requires an adherence to a moral code, but also an understanding of probability. Also, the consequences of any action taken must be fully understood before one can make the judgement whether or not it is better to go through with the action or not to pursue it at all. Most people are of the inclination that "lack of certainty is due to lack of knowledge and that if we knew the whole situation . . . we should be able to predict the future with certainty." (Emmet 208), but absolute knowledge is impossible, so decisions can rely only on existing facts. The facts which exist can not be disputed, but they must be in a sufficient number if a decision is to be made. In essence, one must respond to the question of what this sufficient number might be, and this number must be determined in a manner such that the likelihood that the facts are a good approximation of the whole picture is high compared to the potential consequences of one being wrong.
In some cases where certainty does not exist, one can employ a simple mathematical probability. For instance, if one were asked the question 'Is it going to rain today?' and the conditions were such that they indicated there would be no rain (ie: not a cloud in the sky), and the weather services had predicted only a 5% chance of rain, it would be a fair and justifiable statement to make to say that it would not rain that day. Of course, this is a statement and not an action, but the action of leading someone to believe that it would not rain of the same conditions existed would also be justifiable. One must take note, though, that in such a case the potential consequences of a wrong decision made (ie: if it did, in fact, rain that very day), are minimal. The consequences must decrease in severity...
