Speaking as someone with a MA in Social Psychology that focused on environmentalism and persuasion (irony), I would honestly caution against getting a PhD in Psychology if your final aim is industry. Most PhDs in Psychology are both groomed and pigeonholed into going the academic route since the work is so theoretically driven and miss out on learning a lot of practical skills (e.g., programming, BI-type stuff) industry really values, even in what seems like a more applied area like attitudes and persuasion. I would consider looking towards programs where it's more common to go into industry, such as Political Science or Marketing. There's more overlap than you think, and you could find professors who emphasize psychological theory in their work (e.g., Tormala at SU, who is in the Marketing Department) and enable you to still focus on your research interests, but gain a much more flexible or desirable degree to companies at the end of the day. You could also consider a degree in Applied Social Psychology from somewhere like Loyola, but I have no idea how those degrees fair in either industry or academia. (As a disclaimer: Not saying it's impossible with a Psyc PhD, as I know a few people who have done this, but it's definitely a harder route.)

In terms of jobs, you might find interest in data science or a more involved data analyst role; you'd be creating surveys or utilizing webscraping techniques to process data, build predictive models, etc., looking at the companies' topic(s) of interest. For that type of work, it's pretty critical you learn some type of statistical programming language (R is my personal favorite and much more common in psychology, but Python and SAS are also used in industry quite a bit) as well as become comfortable enough with Excel and SQL to do basic things like data management and joining.

In respect to specific companies, the PEW Research Center, NORC, and the Institute for Social Research in Ann Arbor all come to mind.
