While there isn’t a specific aesthetic conceptual art follows, during the 60s and 70s there were certain trends and concepts that were widely adopted. What united many conceptual artist was their discomfort over the "institutionalized state of the art world”, with “good” art or “bad” art being determined by the marketplace rather than the makers.
Those that gained from this system were a small group of (mostly male and white) artists and members of the elite social class who sold and collected the work. In the 1960s, there was a shift, a sense that if art catered to this world then it will surely not strive to challenge any status quo. Conceptual artists and theorists looked closely at modern art practices during that time but ultimately found a continuation of abstract and minimalist motifs, rather than anything that pushed boundaries.
As a result in the late 1960s, a form of conceptualism known as “institutional critique" began emerging. Practiced by artists such as Hans Haacke, Daniel Buren, and Marcel Broodthaers, institutional critique continued the notion of idea-based art, but usually in the form of installations that questioned the assumed function of the museum. Many conceptual artists saw museums not as a neutral hall for the exhibition of works to the public, and instead as places invested in promoting certain artists and selecting “important” works whose sales will benefit the trustees and the established art world. The works created to challenge this were often complex though, as these pieces of art were often staged in the very places they were critiquing.
