I've noticed there's been a strong aversion and tone in regard to companies tracking emotional and cognitive signals to make decisions.
I'd like to get people's opinions on this and possibly understand if there's a frame where you would be FOR this in running your own startups.
What is your stance on businesses tracking Emotional Intelligence?
Would it make sense if this was done in the benefit of your company or customer base?
I strongly suspect it isn't the case. What you're really after is detecting user frustration or user fulfillment: That is a more complex emergence where emotions can be a symptom.
Reading those emergent signals is well within expectations. Users probably do hope you'll make their lives easier or better, that's why they're using your product :)
Another consideration is that, frankly: Reading emotions to make a business decision implies that your product is the user's entire world. Even for mentally engaging products involving something like therapy, it's not: You can have an angry user that loves your feature, and a happy user that hates it.
Emotions are messy, fluid, imprecise, and circumstancial. And in many people's opinion, simply nobody else's business -- It's a good question to wonder why, but as a baseline, that's just the way it is for many people.
