premise: Invitation to Sociology: A Humanistic Perspective is a 1963 book about sociology by sociologist Peter L. Berger, in which Berger sets out the intellectual parameters and calling of the scientific discipline of sociology. Many of the themes presented in this book were later developed in his 1966 book "The Social Construction of Reality", coauthored with Thomas Luckmann.
hypothesis: Peter L. Berger died in 1966.
reason: We don't know when he died, it's unlikely he died in 1966 because he wrote a book in that year, but it's possible he wrote the book in the beginning of the year and died in the end of the year, we simply don't know. It's difficult because the text says he wrote a book in that year, so the system assumes he couldn't have died in that year.
