The fundamental reason why most instructions read like a coded message from a hostile alien civilization is a psychological phenomenon known as the curse of knowledge. This occurs when an expert forgets what it is like to be a beginner. To an expert a process is so ingrained that they might skip the part about actually turning on the stove because they assume the heat is a cosmic constant.
This mental gap creates a bridge to nowhere for the poor soul holding a spatula and a dream. When we know a subject deeply our brains compress complex sequences into single effortless thoughts. We do not see twelve distinct steps to assembling a bookshelf. We see a completed bookshelf and wonder why the rest of the world cannot just make the wood pieces hold hands and behave.
This leads to vague phrases like rotate until it feels right. These are the linguistic equivalent of a shrug. Feeling right is a subjective emotional state and not a measurable unit of torque. Another massive hurdle is the false assumption of common sense. Writers often believe that certain actions are universal truths when they are actually learned behaviors.
This is why you find yourself staring at a diagram that looks like a Rorschach test while trying to figure out which side of a washer is the front. Creators of manuals often suffer from a lack of empathy for the confused. They are blinded by their own efficiency. They write for an audience of themselves.
This self centric perspective ignores the fact that a user might be tired or hungry or perhaps just not naturally gifted at deciphering grainy black and white photos of plastic tabs. Experts often fall prey to a cognitive bias where they assume that if they can see the solution everyone else should be able to see it as well. It is a failure of imagination that results in thousands of people crying over a pile of Swedish particle boards.

Language itself plays a treacherous role in this comedy of errors. Words are slippery things. One person's lightly seasoned is another person's pepper sprayed dinner. When instructions use relative terms instead of absolute measurements they invite chaos into the kitchen. Technical writers also frequently fall into the trap of using jargon that sounds impressive but explains nothing.
They might tell you to calibrate the longitudinal actuator when they really mean wiggle the silver stick. This desire to sound professional often outweighs the need to be understood. Furthermore the people who write the instructions are often not the people who designed the product. This creates a game of telephone where crucial details get lost in translation. If the writer has never actually tried to build the item themselves they are essentially writing a travel guide for a country they have never visited.
