Most citizens, at least in the West, "know" their political environment. For instance, which issues are "important" and party platforms, mostly from soundbites of information.
Politics often drive political perspectives of citizens, not the other way around. So, I would rather citizens be actually educated on the political process and philosophy in order to be a "participant" rather than have a surface level understanding in order to be a "voter".
Indirect participation only exists when representatives are driven by voters, not the other way around. Futhermore, voters need to be educated on political issues in a manner that is mindful of political history, philosophy, and critical analysis thereof in order to then move representatives rather than be moved by representatives.
The biggest issue is that most citizens do not know their own interests and often hold beliefs without understanding the ultimate reasons as to why they do - ideology. Citizens, thus, rarely agenda-set or frame issues through what they value, but develop surface-level or (at best) substantive understanding, but ultimately citizens are not consciously inputting their own values into a political system.
