What do you do if your research results in failure, and how can you learn from it?

Is good to consult as much materials that are related to your research and also get access to the expert in the field your working on, because of some hindrance along the way that will help in getting yourself out, in addition to that negative outcome may be a starting point for another researcher.

I'm not sure if 'failed' in this context means that a journal refused to publish your research or that the evidence you amassed didn't support the conclusions that you had hoped to make. If the former, I'd suggest trying somewhere else, and if it still fails put it on an Open Access website like Research Gate for others to read even if peer reviewers turn it down. If the latter, then you must seek other conclusions.

No research fails, what you have is limitations of research and a good researcher will be able to identify those and make note of them including them in the write up. Was the population unbalanced by gender, age, ethnicity; sample size too small. A big criticism of psychological research is most of it is done in Universities in Western Countries resulting in inconsistent findings when applied in different populations. The University subjects tend to be European/American and in their 20s or 30s. The limitations of one research opens the opportunity for further research.

Mostly from an in vivo research perspective, remember going in that your research is a step-wise process from establishing your model, testing positive controls, and then running your unknowns with dose-response and time curves--that's a lot of cross-over studies to do it right! Doing in vivo research means expecting unexpected failures from a wide variety of sources, but knowing you will eventually get reliable, reproducible data. You also have very defendable results if you are +/-20%: animals may be considered "furry test tubes," but they are individuals with intrinsic variation. And stick to your guns when management wants publication and/or movement to the clinic without repeating the experiment at least 3 times! Good luck!!

Observe other's failures, distance your ego from the failures overcome emotional barriers, and confront the failure head-on. Avoid sour grapes. Unlearn/Learn, what new knowledge or skills do I need? Learn from others' failures. Establish a learning process.

Research is a scientific process and there must be a proper research design and methodology that guides the research process. Improper or poor research design leads to failure. Therefore, we need to embrace utmost care while designing the research. One possible way to ensure proper design is to undergo thorough literature search that helps us to understand the phenomenon in hand, discovers underlying variables to be considered and build the premise for research design.

O feedback honesto é fundamental. Muitas vezes a falha está no projeto, o que pode ser complexo e, algumas vezes, impossível de resolver. A defini??o da pergunta da pesquisa e os métodos usados para tentar respondê-la s?o pontos fundamentais no sucesso de qualquer pesquisa. Contar com a ajuda de um mentor ou orientador nessa fase é crucial.
