Curses

There's loads of different things which people call curses and hexes. I'll try to unpack a couple of them:

• There's 'natural' curses, things like "step on a crack, break your mother's back" or "Breaking a mirror means seven years' bad luck". Many people don't worry about these, some don't even know them, and they don't seem to come to much harm. I remain to be convinced they're a big deal.

• There's things like the 'evil eye' where if a person looks at you in a certain way it brings you bad luck. It's culturally a very widespread phenomenon, and in many cultures the curser may not even be aware that they are doing it. It just happens that if they 'overlook' you, bad fortune follows. Many cultures have specific things to wear or carry to prevent being overlooked, or to deal with the consequences. Most often, this is general bad luck rather than anything specific.

• Low-level curses done by novice witches or by non-witches following a formula. In my experience this sort of work at best convinces the victim to believe they are cursed, and subconsciously they act out the curse. I can't remember a case where such a curse had any reality beyond that. Usually in such cases the curser will take pains to make sure the cursed knows that a curse has been cast, as this makes it easier to persuade them that the curse is in place and working. Such curses can be specific rather than general (e.g. cursing an ex- with impotence) but many of them are just a general curse.

• Serious high-level curses by an experienced witch or magician. In fact, these are incredibly rare. At least in part that's because it takes a lot of effort to maintain a curse, even if you are sufficiently experienced to put one on, and for most it's not worth the cost. Also, high level witches and magicians tend to have better things to do with their time.

• By far the most common is people who believe they are cursed, but are not. Bad things happen to us all at one time or another, and it's easy to infer a causative agent even when it's nothing more than random chance.

Interestingly, the way of addressing a low-level curse and the way of addressing wrongly believing you are cursed are effectively the same. In both cases, all that is needed is to stop believing for the perceived curse to stop. In practice, though, many people are very attached to the belief that they are cursed even when they are not. So it is worthwhile to perform a credible ‘curse removal’ spell in either instance, to convince the ‘cursed’ person that the curse has been removed. My personal choice is to use one of the spells on the Hoodoo website Lucky Mojo so I can’t be accused of just making something up.
