The rationale often provided for including genetic information in prevention science is that it could allow interventions to be individualized based on child characteristics. But as a field it is worth taking a collective step back to ask if that possibility is something we realistically envision. Do we really envision a future where we will be genotyping individuals to determine access to or placement into prevention intervention programs? That possibility seems highly unlikely in a school or community setting. And genotyping children to make decisions about prevention placement also carries a host of ethical questions. Genotyping is expensive, and genomes carry a wealth of health information, much of which will be unrelated to the original outcome of interest. There is currently an active discussion in the field of genetics about the return of incidental findings (Christenhusz, Devriendt, & Dierickx, 2013; Green et al., 2013; Wolf et al., 2008). That is to say, when we conduct a genome-wide screen (for example), to try to find genes involved in alcohol dependence, or, in the future, hypothetically, to create a score to assess
