In statistics, self-selection bias arises in any situation in which individuals select themselves into a group, causing a biased sample. Drawing insights from a biased sample is probably worse than having no clue about what you are dealing with. On top of that small samples are dangerous in a way that they can give an impression that the data is skewed in a way which in reality is not true. Questions that inquire about more than one topic, yet allow only one answer, are known as double-barreled questions. All the answers will be lumped in one variable thus being very difficult to analyse and find out who meant what when answering. It's not a bad idea to be mindful about the analysis once you know your shortcomings and very careful when generalising your findings.
