What does "them" refer to in this paragraph?

Hello? I've got a question about a pronoun. In the paragraph below, 'them' was used twice in the highlighted sentence. What does 'them' refer to in the sentence. I originally thought that it should be 'the issue'. However, 'them' is plural, so I think it can't refer to 'the issue'. Thanks in advance.

Very briefly, the complex individual is one who can see things from another person’s point of view and who is flexible in his/her thought processes. For example, they are able to change their minds on an issue in the light of new information rather than rigidly “sticking to their guns.” They also tend to avoid what might be called “black and white” thinking. For example, the positions of others on an issue are not lumped into the two categories of those for them and those against them but rather shades of differences or gradations of opinion are recognized and taken into account. Thus, they realize that the truth of a matter often lies somewhere in between two extremes. Last but not least, the complex person seems better able to hold off on a decision allowing more information to be taken into consideration.
