are experiment results always the same in science and in other areas of knowledge?

Question

in science its claimed that experiments are replicable but is this possible or desirable in other areas of knowledge?

Answer 1

It must be repeatable and when it will not repeat u missed the target,and don't know why.

Answer 2

Experiment results are not always the same in science. There is nothing mysterious about science that makes experimental results magically end up the same. I don't know of any field of knowledge where this happens.

Scientists would like experiments to be the same, but nature doesn't cooperate, and a lot of work goes into make it possible to compare results.

Some of the things you have to deal with are things like experimental error. Things just naturally fluctuate. Try bouncing a ball up to exactly the same height ten times in a row, or anything else EXACTLY the same way over and over again. It's tough.

Some of the things scientists do to overcome these issues are:

* Statistics and sampling: Rather than record a single trial, repeat the trial a bunch of times and average the results.

* Controlling the conditions and environment. Instead of bouncing the ball by hand by throwing it at the floor, try holding it up to the roof and letting it fall. It's easier to repeat. Lots of lab equipment is intended to simply do things very consistently in one way or another.

Other ideas include eliminating extraneous variables, and noting specific details of how you do the experiment so someone else can repeat every detail of what you did.

Then there's the matter of external review. Science tries to make this very systematic with journals and the peer review process. But it all boils down to having others study and try to repeat what one person did and reported.

There are many fields of study which try to do similar things. Some times it looks a lot like science. Sometimes it looks very different. Not all the methods are equally applicable. A biology study which involves the use of specially bred mutant mice uses methods that you'd never think to apply to human beings in a sociology study, so you set up and perform those studies in very different ways.

But at the end of the day there's nothing so different about science than anything else. The trappings of science--the equipments and institutions and the language and complicated theories--are all driven by a fairly simple, common idea of relying on tangible evidence and repeating results.

Answer 3

Experiments are never truly replicable. Tiny variables that are impossible to control will always have a small effect. However, these don't really matter most of the time.

Experiments in non-science subjects are even harder to replicate perfectly, because they depend on things far more variable than nature (such as the human mind). However, with large sample sizes and a reduction of variables, socialogical and physcological experiments can often get very similar and accurate results.

Answer 4

There ARE no other areas of knowledge. The essence of scientific knowledge is that it is possible to prove that a proposed theory of wrong. It is possible to show that the usefulness (i.e., predictive power) of any theory arises exclusively from its refutability. I have generalized "science" here to include anything about which a refutabile theory can be formed; that includes things like history and music, but excludes religion.
