Books bring together years of empirical research into broader narratives. They represent the judgement of individual authors while remaining grounded in the evidence developed through CGHA's wider research programme.

An investigative narrative revealing how smartphones, deregulation, and pandemic isolation turned America’s pastime into its newest addiction — and the book behind CGHA’s gambling research programme.
Every project undertaken by CGHA begins with evidence. We collect field data, undertake surveys, analyse markets, study institutions and measure outcomes before drawing conclusions. Reports, books and commentary are all built upon that evidence.
One thing that distinguishes CGHA from many organizations is that we do not see the reports as the primary product.
That is also why much of the work published here appears under the name of the Center rather than individual authors. Individual researchers make essential contributions, and books and journal articles are properly attributed. The underlying evidence, however, is intended to become part of a permanent institutional resource that others can examine, challenge, refine and build upon.
