I'll (obviously) be voting no. But I have come up with a way to sort of disprove superstition. It goes like this:

Make a list of all the possible good luck charms you can think of...
- Rabbit's Foot
- Four Leaf Clover
- Horseshoe
- The Number 7
- Golden Nuggets
- Etc., etc.

Now make a list of all the possible bad luck charms you can think of...
- Black Cat
- Ladders
- 13th Floor
- Broken Mirror
- $50 Bills
- Etc., etc.

If we were to (theoretically) remove ALL possible items on both lists, would there still be good and bad fortune in the world? The answer should be YES, of course!

Would any superstitious person like to refute?

the good/bad luck from each item you listed would just move on to something else.

This also explains why the luck isn't as observable today as it was in the old times. When black cats were imbued with bad luck, it was a set amount per cat. As the cat population increased, the luck per black cat decreased to the point where it is only mildly perceptible now, and not testable with the weak statistical tools we have today.

Same applies to all other objects.

No, and anyone who tells me something is bad luck I will blatantly do in their face to show how silly it is.

Except for my grandfather, when he used to be a fisherman he believed that someone whistling on his boat would bring bad weather. It's about the only rule I remember him having on the boat. He once grabbed his helper by his hip waders and threw him in the water for not listening to aforementioned rule.

I'm skeptical, but I'm also highly suggestible. If I walk under a ladder, I'll often feel very nervous for a couple of days, and I might experience some negatives based on the psychological response. Similarly, good omens can be encouraging.

I'm just regular stitious.

If I start running good I'll leave the same song that was playing on repeat sometimes for hours and hours...I don't actually think its doing anything so I wouldn't really call myself superstitious

Not in the slightest. I do like to insist that the world is against me when I have a run of bad luck, though. Also, I like to dismiss my poor performance as bad luck (to others, not myself; otherwise I wouldn't be capable of this thought) which means that I can claim to be unluckier than average. That means that when I do well, I have done it despite the world being against me. If I do poorly, well, what chance did I have anyway with the luck I have? Part of me is sorta half serious in the heat of the moment because I'm pretty competitive and I hate losing and I get angry / irrational. Another part of me knows that this is all BS but lets me say it anyway cos I know that it'll make me feel better.

As far as black cats / umbrellas / ladders etc.. go, I just wasn't brought up like that. My mum'll sometimes tell me not to tempt fate but she doesn't believe it. It's just a figure of speach to her. I don't say it cos I think it sounds idiotic but w/e.

Ha, you found SMP. Awesome!

In practice yeah sometimes I'll act superstitious, like playing the same song/album/playlist when running good at poker or whatever, but the rational part of me is always saying to myself 'you know...that's all a bunch of BS it doesn't really work'. Same thing with Karma, I know it doesn't really exist but if something bad happens to someone that deserved it i'll usually remark that it was Karma but I'm not really serious.
