I don’t think it is likely, I also speculate aphantasics may be generally less-exploitable than the average person. Since imagery, whether seen or imagined, has been shown to play a critical role in emotions, it is possible that communicated motivations would be less effective at persuading aphantasics, and people/animals will not do something unless they have motivation to do so. Now motivation can also come from things such as coercion, however most motivations are internally generated such as curiosity, passion for an activity, a feeling of purpose, or fear of missing out, loss, or failure.
So imagine law enforcement was trying to recruit people by saying, “our enemies are trying to kill us and if we don’t do our duty, they will get our families!” or “you will climb the ranks and be general in no time, and the president will be asking you for advice on a regular basis.”. The average person will see imagery representing these things, and presumably experiences the emotions their mind relates to these ideas.
And as discussed, motivation is often emotional in nature. So if emotions are more effective signals of persuasion that reasoning, than it is reasonable to speculate aphantasics are less likely to be persuaded to do something they don’t already have some relevant emotional connections to.
