A ccording to indicators of political repression currently used by scholars, human rights practices have not improved over the past 35 years, despite the spread of human rights norms, better monitoring, and the increasing prevalence of electoral democracy. I argue that this empirical pattern is not an indication of stagnating human rights practices. Instead, it reflects a systematic change in the way monitors, like Amnesty International and the U.S. State Department, encounter and interpret information about abuses. The standard of accountability used to assess state behaviors becomes more stringent as monitors look harder for abuse, look in more places for abuse, and classify more acts as abuse. In this article, I present a new, theoretically informed measurement model, which generates unbiased estimates of repression using existing data. I then show that respect for human rights has improved over time and that the relationship between human rights respect and ratification of the UN Convention Against Torture is positive, which contradicts findings from existing research.Notes: Proportions closer to 1 indicate that the dynamic standard model outperforms the constant standard model at predicting the original repression variables. Proportions closer to 0 indicate the opposite. Proportions at 0.50 indicate that both models are predicting the items with about the same amount of error relative to each other. The dynamic standard model does a much better job of predicting the original repression variables, especially the event-based variables.
