Not if you don't know either to begin with! And while some of them were actually easy to look up on google, some were not so intuitive at all, and I came across them more by their relation to the other terms.
But again, that's not an excuse. The UN may actually be more recognizable than The United Nations, it still didn't excuse the use of The UN without first identifying it as the united nations in any political science research paper I wrote. This is a very common practice across most academic fields, even when it is expected the audience will be as familiar with the abbreviation or more so than its elongated form and even if they are expected to not think of any other similar terms from other fields because they are outside their area of study.
