Created between 1977 and 1979, Truisms are concise phrases that encapsulate complex ideas in simple, often confrontational language. Holzer originally disseminated these texts anonymously on posters throughout New York City, blending them seamlessly into the urban environment. The anonymity and ubiquity of the posters encouraged passersby to engage with the statements on their own terms, reflecting on their meanings and implications.

The "Truisms" cover a wide range of topics, including politics, social norms, identity, and human behavior. Each statement is designed to be both provocative and ambiguous, encouraging multiple interpretations. Phrases like "ABUSE OF POWER COMES AS NO SURPRISE" and "PROTECT ME FROM WHAT I WANT" invite viewers to consider their own beliefs and the societal structures around them. This broad thematic scope ensures that the "Truisms" remain relevant across different contexts and eras, resonating with diverse audiences.

Holzer’s use of public space for the "Truisms" was a deliberate choice to reach a wide audience outside the confines of traditional art galleries. By placing these texts in everyday settings, she democratized access to art and provoked spontaneous public discourse. The simplicity and directness of the "Truisms" made them easily digestible, yet their content often challenged viewers to confront uncomfortable truths about society and themselves. This approach transformed mundane urban spaces into arenas for intellectual and emotional engagement.

The success of the "Truisms" series led Holzer to explore other mediums, including electronic signs, projections, and even T-shirts and mugs, further broadening the reach of her messages. The adaptability of the "Truisms" to various formats underscores their versatility and enduring impact. Whether displayed on a billboard, projected onto a building, or printed on everyday objects, the "Truisms" continue to engage and provoke audiences worldwide.
