And it will always be restricted in a specific scope. When you claim something is simple, you have to define what you mean by "simple". In many cases, people just ignore this. they want to measure something without defining a proper measure.
Even a measure is defined, as I said, it will be restricted in a specific scope. It may not be the simplest in this scope, but it may be the simplest in another one. So even for those people who believe occam's razor is the unbreakable law, the complexity cannot be used to decide whether something is scientific or not.
