It is a brief and combative essay that arises from a very specific concern: the growing social rejection of well-established scientific truths, from climate change to vaccines. Lee McIntyre does not write from an ivory tower, but from the direct experience of having engaged in dialogue with science deniers in real contexts. His central thesis is clear: discussing data is rarely enough; what is decisive is rebuilding personal trust and opening a space for conversation in which the other person does not feel attacked.
The book is successful in being practical without falling into simplifications. It advocates listening before refuting, finding common ground, and avoiding public humiliation—strategies that, when properly understood, have a solid human foundation. In that sense, it reminds us that truth is not imposed by arguments alone, but requires a prior bond of credibility. However, at times, its approach may seem naïve or overly optimistic regarding the interlocutor’s willingness: it is not always possible to engage in dialogue with someone who has made denial an identity position. It also lacks a deeper reflection on the cultural and moral causes of resistance to science, which go beyond mere misinformation.
All in all, it is a useful and timely book, especially for those who face such discussions in their immediate environment. It does not offer magical formulas, but rather a sensible guideline: without respect and patience, there is no possible conversation; without truth, there is no lasting solution either. It conveys a strong confidence in scientific consensus as a criterion of truth, without sufficiently qualifying its philosophical limits.
