It is often claimed that scientific results must be replicable. Is this possible or desirable in other Areas of Knowledge?

As the worldly wisdom suggests always think twice and try to ascertain if you are right. The replication of scientific results makes them reliable, if it weren’t so, we couldn’t rely on any results, because then lots of errors would have occurred and no perception which results are right would be found.  People are in need of generalizations, they imply that it is easier to live when everything is orderly put into drawers, so they are trying to divide everything in groups and decide, whether the information is reliable or not and the more replications are done the bigger reliability of results is. However, can we always do the replication and why do the results differ?

In natural sciences experiments are made frequently, the science is more or less based on the results of experiments and whether the hypothesis is proved or not and it is not so hard to repeat the experiment once more, however the identical results hardly occur, just the trend of the results. For example, biologist investigates whether the temperature has the effect of the rate of cell respiration. After he had replicated his experiment three times, his results showed that the temperature fasters the cell respiration, but he actually didn’t received exactly the same numbers in every retry. Nothing happens identically, however the tendency how will something happen is found and then further deductions uses this conception. Assume that at the same time other person did the same investigation and safely reached kind of the same results. So, the results depend just on the experiment itself, not on who holds it and if the person would keep exactly on instructions in this investigation he will draw a conclusion that cell respiration depends on the temperature.  Furthermore, the more experiments are made the more accurate amplitude, how can results vary, can be made, however the scientists are not determined, because of the lack of time and widely spread competition feeling, to repeat their experiments lots of times and test it in various ways.

Meanwhile the situation of replication in humans sciences soundly differs, the human scientists can’t ensure that the conditions of the experiment while repeating it won’t change as the natural sciences does. The research when changing the objects and the environment might bring totally different results. Furthermore when humans’ emotions or perceptions are investigated, they claims aren’t fully reliable as they can change their opinion extremely sharply. In addition, the human’s perception of the world and things which are happening depends on his own experiences, personal beliefs and the environment, he has grown up, and so to generalize people’s ideas is ...
