This just reminds me of the r/cognitivetesting subreddit. Filled with a bunch of people worried about their cognitive tests and "intelligence" without focusing on doing any real work. For me this seems a completely futile enterprise. Intelligence is utilitarian; an instrument. I think everyone should strive for impact; to do great work. In doing this you will find your limit (or not). I've always found people that obsess over "actual intelligence" to be people who are not really focused on the work but instead on ego-stroking.
If you fry akara in a good location, after all cost, you make N20/akara and you sell 500 pieces per day. That is N10k/day, N60k/6 day week and N240k/month. Better than bank job.
Okay, on an individual level, how do you fight what you call the "olodo uprising"? I think that's the best way to approach this trendy conversation.
Please don't tell me about the educational system. I am asking what you, as an individual, would do.
