I did 2 customer surveys in the last days and for both they only had a forward button (or even worse: auto forwarding on selecting a choice), but no back button.

Why would you remove that? That's so stupid. Especially with touch screen the answer given might have been by accident. Why would you not give people the chance to give you correct answers??

It was standard to have back buttons last time I did such a survey.

The rationale is that a later question might prejudice your response to an earlier question, so to eliminate bias

Later questions might give context for the earlier questions and going back would let people answer the first question accurately instead of skewing towards the answer they want.
