As a writer, this is something I often have to consider and pay close attention to while I plan, write, edit, and revise. Early on, it’s easy to write yourself into a corner or come up with a convenient climax to force your main protagonist into success. This is just another example of growing as a writer to be honest. Lessons learned is the best way but you won’t get there unless you have some astute beta readers looking for these faux pas.
Thankfully, I’ve managed to find some very good beta readers myself. In fact, I would actually encourage (I know this is weird but track with me) you to write into your story small and large plot holes (or inconsistencies), making sure you are aware of them and see if your beta readers come across and puts a big giant “?!?!” next to them. If they do, then I think you’ve established finding a beta reader worth keeping around. Plus, you can trust they will find the plot holes you’ve glossed over yourself.
Caution/Warning!: Make sure you go back and fix those deliberate mistakes before you send your story to an agent. Trust me, they will pick up on it and if it’s especially glaring, they will chuck your query in the waste bin faster than a dog scarfing a burger tossed in the dirt.
How do you fix a plot hole? By writing of course. It may take some passes but the solution will eventually come to you. The best thing to do is not feel overwhelmed if it takes a while. Be willing to sit on it for awhile, letting your creativity go to work while not sitting in front of the screen. In fact, grab a notepad and write down the plot hole. Let yourself do some manual writing for a change and see what comes.
I ran into a minor but glaring plot hole in the first chapters of So Speaks the Gallows after my main beta reader brought it to my attention. I actually had to talk it out with him in order to find the fix. It was actually a simple solution that didn’t require too much rewriting but it did need to take place. I’m glad it did because it actually allowed me to add a layer that otherwise would never have been there. (I’ll reveal what this was later down the road once the book gets published. I’m planning on releasing some behind the scenes/commentary posts in the future but you’ll have to wait for that. Hopefully, not too long of a wait.)
Consider plot holes, mistakes, inaccuracies, etc. to be somewhat a natural occurrence if you’re a storyteller. It will happen because the more complex your story is, the more likely you will forget to consider a plot, setting, or character aspect that will lead to your audience giving you a big red “?!?!”. Try not to get upset or discouraged by these instances. Shrug it off and begin the search for the solution. Once it’s there, insert and revise accordingly.
Call to Action: If you want to seriously treat yourself to some fun plot holes in movies and tv shows, simply go to Youtube and search “plot holes”. You will not be disappointed. Avoid the Disney videos though because these will inevitably ruin future watching of your favorite animated films. But if you’re a diabolical glutton, watch with and then test your children to see how smart they are once they watch those same movies. See if they have the beta reader/critique knack.
