Limitations of science
A few of the limitations of science are: "the scientific method is limited to what can be observed with the senses; the scientific method is limited to the present; the scientific method is limited to telling us “how” a process works, not “why.”; the scientific method is limited in that it is amoral (non-moral); and the scientific method is limited in that it cannot deal with the unique."
Science is often better at studying the present through observation rather than forecasting the future or determining the past. Extrapolations involving the future or past can have a number of assumptions and it is sometimes difficult to predict matters in a multiple variable situation.
Difficult scientific questions can involve a number of scientific fields. Scientific experts are more likely to err when speaking outside their area of expertise.
Another limitation of science is that science is a social enterprise and current societal ideological fashions can impinge on the objectivity of scientists and squash dissent.
The fall of man and man's sinful nature introduces problems into the scientific community such as scientific fraud, scientists engaging in immoral research such as eugenics, egotistical scientists making proclamations beyond their expertise and scientists actively suppressing various truths (see also: Suppression of alternatives to evolution and Evolution and Cases of Fraud, Hoaxes and Speculation and Atheism and deception).
Scientific fraud: Additional information
The scientific enterprise is greatly enhanced if a society is virtuous. On the other hand, a great deal of errors are introduced into the scientific community in a culture which lacks integrity.
Scientific community and fraud in science publications
Social science literature has major problems
- "The great climate science centres around the world are more than well aware how weak their science is. If you talk to them privately they're scared stiff of the fact that they don't really know what the clouds and the aerosols are doing."
