You've probably heard of the Butterfly Effect, but if you haven't, it's basically the idea that one small thing can lead to a whole cascading chain of events and this is usually talked about in the context of a person's life to sound profound, or play with concepts of time travel, or ruminate on regret, or celebrate how amazing it is that one little thing made such a big thing happen.
This way of thinking tends to make a person's life trajectory sound extremely brittle and I'm going to attempt to show a bit what's wrong with it and how it hides behind Great Man Theory - the idea that history is primarily defined by the movements of "great people", usually men (side eye at patriarchy), who had some kind of dramatic impact that changed the course of history.
So what do these do have to do with each other? What they have in common is that they attribute outsized influence to things that don't deserve it and they reduce lots of complex dynamics (such as gradual transition from one state to another, quantitative to qualitative; negation, how the caterpillar negates itself to become a cocoon and the cocoon negates itself to become a butterfly and so on) and turn it into a laser focusing on a singular factor or decision.
I'm far from an expert on dialectical materialism, but I feel confident in saying that neither Great Man Theory nor the Butterfly Effect (at least in its colloquial use) hold up to it.
Let's consider an example, first we'll look at it the way the butterfly effect narrative might write it.
A person, we'll call him John Butterfly, graduates high school and he is deciding where to go to university. A chance conversation with a stranger steers him toward studying abroad and he goes with this idea. In this other country, he meets a person who he becomes romantically entangled with. This person knows an expert in the field that John Butterfly is planning to study in. The expert helps him learn better and has a great opportunity for him after he graduates university. He eventually gets married to the person he hit it off with, gets a great job due to the connection, and goes on to win awards and have many babies. And look at that, baby of John Butterfly. You only exist because John Butterfly just happened to talk to that stranger and just happened to decide to go study abroad. Everything after that sort of just fell into place, like it was pre-determined. Isn't life profound and strange.
Now let's look at it with another lens.
John Butterfly graduates high school and is deciding where to go to university. He is socially positioned such that he was able to go to high school and graduate, and there are options when it comes to university. He lives in a place where studying abroad is something people talk about and tends to be an option, at least to some degree, and stacking factors up to that point, ones he may not consciously be paying attention to, lead to him feeling more interested in getting far away from home than sticking around. Maybe he has a shitty family life or he has an especially adventurous spirit and developed an interest in other cultures as he grew. Anyway, he's already open to the idea when it's brought up to him because of factors in progress at that stage. For some reason, we decided to mark history as beginning when he met a stranger and decided to study abroad. Not sure why. He's been around for over eighteen years. Civilization has been around for much longer than that, though western civilization has yet to appear.
Anyway, the class/caste of capitalism and modern programs of cultural exchange have already set the stage for him to do something like this. It's expected that some people will study abroad. Further, some people will meet a person who goes on to be their sweetheart in university. Some will also divorce them later, or meet many who they go through and never settle down. These are normal but also not inevitable. Some of it's luck, which is a thing capitalism sorta brings with it. Capitalism has big casino vibes and like a casino, it's the house who wins in the end. John Butterfly is less a profound story about little decisions and more of a success story for capitalism to hold up and say "See, it works! But how does it work? It's a mystery. Life is so mysterious, wow."
It's not so mysterious. He got some nepotism style help from the connection. I forgot to mention he's actually an alcoholic at the end of this and the awards are something he displays in his overpriced house at dinner parties. Most of his kids haven't called him in a while.
You see after it was going so well, he tripped on a banana peel and got hooked on opioids. Then he turned to alcohol. He near went bankrupt from the medical bills, in spite of having more money than a lot of people do. Must be the butterfly effect again. Not the medical system that is squeezing him or the doctors who prescribed him addicting medicine because of capitalist pressures behind it. Not the companies that spend millions or billions on alcohol ads and stores. And the banana peel, well that was an unexplainable weather event. It was actually blown in by a hurricane, so not humanity's fault. I mean, the hurricane was happening this particular time because of climate change, but that's not real anyway, right.
I don't know quite how I got into extreme sarcasm mode, but hopefully I am making the point, a little bit. Our lives are complicated, the systems going on around us are even more complicated, and the butterfly effect trivializes and ignores all of that so it can individualize and create an arbitrary snapshot of when history began and ended. Much like John Great Man's contributions to history. How he invented the windmill by staring at branches moving in the wind for thousands of hours and sustaining himself on pettiness, while ignoring pleading insistence that he feed himself.
Dialectical (and historical) materialism shows this to be folly. Many things considered random or weird can instead be traced back to long-running material factors, combined with the superstructure society side of things, and the inner world factor of individuals acting upon it.
I think a good question in the face of a fantastical butterfly effect chain is, "Why was this possible in the first place? What was going on in the larger world that made this possible? This story that is made up of such seemingly profound change, where 'one action' could dramatically change the course of events?"
Cause damn, if changing the course of events was that simple, I'd just find the right hat to put on and set off the end of colonialism, ya know.
A good analogy would be a domino effect with ever larger pieces. Yes, a small piece can lead to huge pieces falling later, but someone had to set the pieces first.
Yeah, domino effect makes a lot more sense to me, since like you say, it implies pieces were set first. Whereas butterfly effect comes off more arbitrary as to starting point, and cause and effect. Like the fall of the USSR could probably be said to be a domino effect, because of the dependencies that international working class efforts had on it, as well as the power vacuum that it left to the imperialist west to fill up with more virulent anti-communist and neo-liberal policies.
Yep. Butterfly effect shaped the universe. We need to recall the difference between lay theory and scientific theory.
Everything in the known universe can be expressed as a mathematical equation, and further can be condensed into binary, hex (I can sometimes see the forest, individual trees is my weakness, with these sorts of things -- a vague understanding of the overall process, the intricacies can be aptly described as Achilles' heel).

That aside, while we strive for what sh/could be, we work with what is, to get there.
I maintain exploring Machiavelli can aid the process.
