Final answer:
The statement "'Echo chambers' increase dialogue and debate on political issues" is false.
Step-by-step explanation:
The concept of "echo chambers" in the context of political issues refers to situations in which beliefs are amplified or reinforced by communication and repetition inside a closed system and insulated from rebuttal. By its very nature, an echo chamber tends to isolate its members from opposing viewpoints, leading to a decrease in dialogue and debate rather than an increase.
Echo chambers can result in the members becoming more entrenched in their own views, as opposed to being exposed to and considering a wider range of perspectives.
