Firstly the big problem with this question is the use of the word “proven” this is because this is not scientific and thus would never be thought of in a research experiment. In this blog I will absolutely rip this question apart due to it being unscientific.
The biggest problem with the idea that research can’t be proven, is that some conclusion use deduction and induction to create conclusions. This is a problem because both methods of created a conclusion are far to generalized to create a coherent hypothesis which can be proven completely. For example if a conclusion has been created under deduction this conclusion would be true Alfred is fat and likes cake, thus all fat people like cake, however what if a fat person likes pies instead and is allergic to cake? This is disproved a theory. Very similar in induction e.g. if you observe 3 fat people who like eating cake, does this prove that all fat people eat cake. Of course it doesn’t, it means that 3 fat people like cake, the next fat person who you meat hates cake and is obsessed with pies. Thus this hypothesis is dis-proven.
However surely if there is no problem with you hypothesis it must be correct. For example Pavlov proved that animals salivated when seeing food. He did many tests on dogs to prove this fact and when in the present of food the dogs salivated and he used about 2 – 3 dogs in each experiment he had to create his theory. This is an example of a inductive test, due to his wide range of tests and the number of dogs he used. This means his experiment must be valid and it is a logical theory because every dog he tested salivated. Thus his experiment had been proven.
This is of course not true, there will still be dogs in the world who don’t salivate when food is put in font of them. Pavlov to prove his statement true would have looked at all the dogs the have ever been and will be. This is impossible, thus researchers use null hypothesizes to explain experiments. Null hypothesizes are hypothesizes which scientists try to disprove rather than prove. This is because it is much easier to disprove a experiment than prove an experiment. In the case of Pavlov and his dogs the reason why his hypothesis is still upheld is for the reason that there insufficient evidence that dogs do not salivate, if there was sufficient evidence his theory would be stopped being credited. This creates a paradox that in this world there are no theories which are proved there are only theories which are just waiting to be disproved.
Overall it seems that there is no way to prove if anything is true, only if it is not true. There are things which are things in this world with are almost true, however these are not proven but waiting to be dis-proven. “Nothing is true, everything is permitted”
