I'm highly skeptical of this.
The text of the study is available. Feel free to address parts that you didn't think were particularly rigorous.
Anyway, it's an interesting result, but possibly has no useful policy implications at the moment. Does the benefit of removing subconscious racism outweigh the financial costs and side-effects of the medication? The important findings are for neuroscience, which is what the researchers frame their discussion section about.
To conclude, the influence of propranolol on implicit attitudes observed in the present study may shed new light on the neurobiological mechanisms underlying implicit prejudice. Given the important role that implicit attitudes appear to play in overt forms of discrimination against out-group members, and the widespread use of propranolol for medical purposes, our findings might also be of practical interest, and require careful ethical consideration. Further research, however, is needed to clarify whether the observed effect would persist with sustained propranolol treatment, and whether propranolol can modulate implicit bias outside the laboratory.
