The authors found that "genetic influences are smaller for trust, and propose that experiences with or observations of the behavior of other people shape trust more strongly than other traits".

    It looks like the trust paper was more evidence against it. This is the full first paragraph of their introduction:

    Over a decade ago, "all human behavioral traits are heritable" was stated as the first law of behavior genetics [1]. While provocative at the time, evidence since then has accumulated to suggest heritability estimates of 30% or higher on assessments of cognitive ability, a variety of psychiatric disorders, and even for most classic personality traits [2]-[4]. Indeed, a few years later, one may even add a qualifier to the first law "All human behavior traits are quite heritable" (italics added). But the question is whether the quantifier "all" is justified. Is all human behavior quite heritable? Or are there exceptions to this law?.

    The introduction of the paper talking about the "laws" on the other hand did seem a little self-serving.
