The left axis is years of seniority.
This isn't a great study in general, because, realistically, there isn't a large range for the work hours. And the majority of them were grouped into one bucket => 4-8 hours.
That's the biggest problem.
The second biggest is that - presumably - not all of the respondents work 5 days per week.
The third is that - without a large sample size - your margin of error is going to cover a pretty big chunk. If your finding is 6 hours +/- 1 hour, 95% CI - that's pretty unsurprising.
You need a large sample size because there are ~115M workers in the US. What are the odds these 104 people are a decent representation of all ~115M voters??
If there's only 10,000 people this applies to that read HackerNews, then - if you fixed everything else - your CI wouldn't be super low.
When you are a developer, and you only count the minutes that you are at your computer coding, I highly doubt many would reach 3 hours per day.
You probably get a few weeks of “real 8 hours” before your best employees find somewhere less oppressive to work and leave your micromanaged company.
Your bad employees will stay because they don’t have better options.
I was the best performing engineer at that company, handling a contract that was worth >20% of their revenue by myself. They loved me at that company, and I wish I had been honest with the feedback I gave during my exit interview, but I just couldn’t tell the guy my issues were with him.
Looking back at it, I understand why I quit, but back then I couldn’t even put it in words. Thankfully, I managed to keep all the friendships I made, including my ex boss.
If you're my boss, and I'm reading your question, will the average boss communicate clearly?
I simply can't sit and focus working for 8 hours a day. Especially if its hard. I'm not a robot.
If I thought you were sitting there just to watch me to try and force me to work more, I'd leave.
I think for me doing dev, 4 hours is about the max before the quality of work drops off significantly.
