KISS (Keep It Simple, Stupid!) is a [minimalist](minimalism.md) design philosophy that favors simplicity, both internal and external, [technology](tech.md) that is **as simple as possible** to achieve given task. This philosophy doesn't primarily stem from [laziness](laziness.md) or a desire to rush something (though these are completely valid reasons too), but mainly from the fact that higher [complexity](complexity.md) comes with increasingly negative effects such as the cost of development, cost of [maintenance](maintenance.md), greater probability of [bugs](bug.md) and failure, more [dependencies](dependency.md) etc.
WATCH OUT: many have started to ride on the wave of the "KISS" trend and abuse the term, twisting its true meaning; for example GNU/Linux Mint has started to market itself as "KISS" -- that's of course ridiculous and all Mint developers are cretins and idiots. **Maximum INTERNAL simplicity is a necessary prerequisite for the KISS philosophy**, anything that's just simple on the outside is a mere harmful [pseudominimalism](pseudominimalism.md) -- you may as well use a [Mac](mac.md).
Under dystopian [capitalism](capitalism.md) simple technology, such as simple software, has at least one more advantage related to "[intellectual property](intellectual_property.md)": a simple solution is less likely to step on a [patent](patent.md) landmine because such a simple solution will either be hard to patent or as more obvious will have been discovered and patented sooner and the patent is more likely to already be expired. So in this sense KISS technology is legally safer.
Apparently the term *KISS* originated in the US Army plane engineering: the planes needed to be repairable by *stupid* soldiers with limited tools under field conditions.

Compared to [suckless](suckless.md), [Unix philosophy](unix_philosophy.md) and [LRS](lrs.md), KISS is a more general term and isn't tied to any specific group or movement, it doesn't imply any specifics but rather the general overall idea of simplicity being an advantage ([less is more](less_is_more.md), [worse is better](worse_is_better.md), ...).
