The correct answer to the question: What is a dangerous possibility regarding individualism in a democratic society, would be: Political disengagement.
This choice is taken from the answer options given for the same question published by other users. The options there were: A: Freedom of Asembly, B: Political disengagement, C: Binary parties and D: Tyrannical rule.
The reason for political disengagement being the right answer, except of tyrannical rule is that, when people become increasingly individualistic, and indeed they lose the ties they have with their society, what happens is not that they will tend towards tyranny, but rather, they will disengage from the whole political process. As they do not care what happens to their society, only what happens to them individually, they will not identify with any political viewpoint, they will not take their own standpoint, or participate at all, because they will not care, as long as their needs are being met. In a tyrannical rule, the needs of the individual will not be met, so that is why it is not the right choice.
