>>812I've never read or heard of any, and I presume there isn't any, because it's not really viable technology.
>>844This, at least in principle.
Shampoo is likely fine (I have never washed my male frogs with shampoo so I can't guarantee that).
>It is scary to imagine how a government or corporation can control thier citizens by making them feel a certain emotion under certain stimuliEver heard of conditioning?
>such as anger when hearing a government opponent Ever heard of public school history courses, status quo, social engineering, mass media, social media, Hollywood?
>or not when seeing a company productEver heard of advertising, product placement, brand image & association?
To go along with the example brought up by
>>844, you don't really need to directly influence testosterone levels when culture makes boys despise who they are, leaves them fatherless or father-hating, raised & taught from the very young age by, almost exclusively, women-strangers (who discourage masculine behavior, because it makes their jobs easier), causes the society to think that, say, hiring, employing, admitting, promoting women (i.e. non-men) is a virtue, or even financially or legally incentivized; you will end up in a situation where some of these boys go as far as voluntarily assuming feminine form and taking estrogen pills (providing that they haven't been involuntarily fed those by their parents since a pre-pubescent age).
You can do much more with culture than you can with direct influence; also, culture is much more sneaky and will not result in a blowback reaction.
I know that a shady team in hazmat suits spilling a barrel of stinky, steamy, colorful chemicals in a water processing plant is much more cinematic than legally and financially encouraging divorce and making the father figure a pathetic bumbling moron in every piece of popular culture. Even more so, robotic drones injecting you with mind control nanobots against your will. However, it's not efficient to carry out a costly procedure on every individual, even if we did have the means to implement mind control this way.
It hurts me everytime tech-minded people are concerned with potential future applications of so-advanced-that-science-fiction technologies, absolutely not cost-effective, not viable; (also, implying that everything about human physiology, endocrinology and mental state is worked out); while we already have highly developed, multi-million, often -billion, dollar programmes achieving the very thing with centuries-old/intuitive knowledge.
