We study the quantized kicked top's dynamics under projective measurements especially with an aim to connect macroscopic realism (macrorealism) and chaos. The kicked top is a classically chaotic system, and macrorealism is a set of assumptions regarding how systems should behave according to classical intuition which is at present being tested in experiments. Using the no-signalling in time condition, a derivative of macrorealism, we define measures of disturbance due to measurements in order to study the effects of chaos. Restricting to cases which allow a meaningful study of this question, our results strongly suggest that chaos is unfriendly to macrorealism.
