It is very difficult to enjoy absolute ethics in political research in the present period. This is because when politicians or groups of folks with specific agendas need a research paper to back them up, they end up paying a university, or research group for a specific outcome. Researchers should be very careful when taking such money, and understand that such strings attached to political research could indeed get them in trouble with the scientific community, or cause controversy with peer reviews.
So what is a researcher to do? Should they not take the money, should they not take the work, or should they find another way around it? One solution is that if you want to do political research you should first;
Decide what you want to research and then go look for the money.
In other words, you have a suspicion that the research will lead to certain results, and you believe those results will be pleasing to one political agenda over another. In this case you should accept money from the political agenda that would benefit from your research if everything works out the way you believe it will.
This way you are not violating your ethics or code of conduct when you take the money. However, if you allow yourself to be approached by a political group to do a research project this can be a huge problem. In that, you know if you do not produce the right results this will be the last research paper you ever do for that particular group, which has that particular agenda. It is so easy for people and researchers to get into trouble in these matters, and it is something I hope you will consider.
