People will tell you that there's no such thing as a dumb question, but that's not true. Anyone who has said to you "There are no dumb questions!" is only trying to make you feel better because you just asked a dumb question. Of course there are dumb questions – the trick is learning not to be embarrassed of them.
Asking basic and (retrospectively) obvious questions is a natural, unavoidable part of learning – literally everyone who learns something new will ask them. The trouble with dumb questions is that we think they make us look like dumb people. They don't, but we feel this way anyway because we're just monkeys trying to make the flashy lights change on rocks we tricked into thinking.
And when we're too afraid to ask dumb questions in public, we turn to the one thing that we know for a fact has seen more dumb questions than anything else in the world and remains judgement-free: Google.
Google is an incredible tool for developers. But it isn't a nuanced tool – it has no understanding of our knowledge level or background, or of the context of the problem we're stuck on. It don't know what we've tried already or what won't be a viable solution for our codebase. We get broad, sweeping results for specific, subtle questions. The information we find won't always be relevant – or even necessarily accurate.
Sometimes, a broad answer is all we need, and that's great – we can snag some code from a Stack Overflow thread and be on our way. But I've found, more often, it leads me down a rabbit hole of blog posts and forum replies about situations that are almost like the one I'm dealing with, but not really. Sometimes I can wrangle a usable answer out of them...and sometimes I get sucked in and find that hours have passed while I've been following false leads, making minor (unhelpful) code tweaks, and changing the error message but not really gaining any ground.
This happened to me yesterday – after nearly two hours of troubleshooting an issue, I finally got so defeated that I Slacked my boss / mentor and asked for help. I hate doing this because I desperately want to prove that I know what I'm doing and don't need anyone's help (spoiler alert: I do not, and I do). I always worry that I'm wasting his time with my dumb questions, and I can't shake the feeling that if I just Googled just a little more, the answer has to be out there somewhere on the internet.
But here's the thing: he solved my issue in two minutes. Seriously. I can look at the Slack timestamps and see that I sent my first message to him at 4:18 PM, and by 4:20 PM he told me what I had done wrong and I was back on track. I didn't waste his time, he could literally glance at my code and tell me what I had messed up.
Obviously, any question with a <2 min answer is probably a dumb one – mine sure was. But do you want to know something even dumber than the question itself? The fact that I spent hours of time trying to fix it on my own before breaking down and asking someone. Does that one dumb question make me a bad developer? No, it doesn't. It happened because I'm a junior dev, and my lack of experience meant I wasn't making the right searches and therefore not turning up the right material. It wasn't a reflection on my intelligence at all. But the fear that it was is what stopped me from asking my boss for help.
When we lose ourselves down the Google rabbit hole in a desperate attempt to solve things ourselves, it's not impressive or "picking yourself up by the bootstraps" or whatever we've convinced ourselves that it is – it's just a waste of time. Keep in mind, I'm not talking about the quick Google search where you read a couple blog posts or watch a 10 min tutorial video and figure it out – I'm talking about the hours of fiddling and banging your head against the wall. My time is valuable, even if I am "just" a junior dev. And even if I can't convince you that your own time is valuable, you probably work for a company that's paying you for your time, and they would appreciate it if you didn't spend hours poking around vaguely relevant JSFiddles.
I could have spent all day Googling, and I don't know that I necessarily would have gotten the answer I needed. Maybe I could have figured out a different way to approach it entirely, or maybe I would have stumbled across the right information eventually...but I can guarantee you, it would have taken way longer than two minutes.
There absolutely are dumb questions, it's just a fact. But you know what – it's so much better to acknowledge that and just ask your dumb question so you can feel silly for 5 seconds and get to move on, instead of wasting hours on it. The question isn't going to get any less dumb, whichever way you choose, so you might as well pick the option that lets you spend less time on it.
ASK YOUR DUMB QUESTIONS. Embrace them. Love them. They are your dumb children. It's wonderful to make an effort at solving something yourself, it really is – but do yourself a favor and timebox it. Set an alarm on your phone; if it hits 30 minutes and you haven't made any real progress it's time to stop Googling, close your 112 browser tabs, and go ask a human who can offer you both experience and context.
