A Moral Dilemna - Should I lead or follow????

Should I lead or should I follow? Sometimes this is a moral dilemma which we face. Consider this situation. It is your anniversary today and also a public holiday. You have promised to take your spouse out to a movie. If you defect on your promise a potentially unbearable cost is imposed. Hence you decide to go to the movie theater and buy tickets in advance rather than risk bearing the cost. Assume that the theater only sells 100 tickets (5 movies 20 seats each) a day of which only 25 tickets (5 tickets for each movie) are sold in advance. Also assume that you did not choose the movie you want to go to in advance. You do not have any information on the relative merits or demerits of a given movie. Hence one optimal selection rule could be to follow others making the choices. For instance if you find that people are quickly making a bee line for one movie, the likelihood of the movie being good is higher and hence you choose to go for that. Like you 50 others are also celebrating their anniversary and the same rules of the game as above apply to them.

Question: Would you want to wait for others to make a choice before deciding?

Obviously the answer is no. Given that there are 50 people and only 25 tickets, if you wait sufficiently long the likelihood of you getting a ticket (for any movie) is virtually zero. Hence this is a situation where leading seems to be better than following. But is this generally the case?

Now lets move to the later part of the evening. You decide that you like to delve into the wild west for the evening and buy tickets to watch the movie titled Crazy Horse. Leaving the cosmetics aside, lets get into the climax. The scene starts with the camera giving wide angle shots of this dusty lil town. People are lazing around with seemingly no work to do. The calm is suddenly disturbed as a fight breaks out between two people in the saloon over the barmaid. As was the case in the middle of the 19th century, disputes were settled with guns.

Let the protagonist be Mr. Sitting Bull and the antagonist be Mr. Crazy Horse. The two are staring at each other with murderous intentions. The townsfolk are scattered around watching. The wild west believed in fair play and there were rules for gun fights. A critical element in any gunfight is that both fighters should have a fair chance and hence drawing the gun too quickly results in foul play which in turn implies that the fighter who draws early will be lynched (implies death through torture of some kind in this situation) by the folks in town.

Now here is the dilemma facing Sitting Bull and Crazy Horse. The only way to survive is killing the opponent. But either of the fighters do not want to draw early and risk getting lynched. Consider the case of Crazy Horse, if he were to draw he needs some reason to believe that Sitting Bull is making the attempt simultaneously. This implies that there is a good chance that he might not make the first draw. But we know that the person drawing first has the maximum chance of success but at the same time also has the maximum chance of being lynched.

And now with the tension gripping, you turn to your spouse and ask her. So my lady would you follow or lead? Essentially the question is put yourself in the shoes of either Sitting Bull or Crazy Horse and then decide what would your choice be.

And so the answer is?????????????????????

Not sure if I am following it...does it mean that I am leading..;)

Well, if it is about making my wife happy, I wouldnt be worried about the cost. I will buy 5*2 tickets for all the 5 movies. Ofcourse, I might optimize a bit by indirectly sampling what my wife prefers without her knowing it... Because, a good movie liked by many need not necessarily be good to everyone, in general...

As to the later part, I was watching one of the cowboy movies recently (dont remember which one...one of clint eastwood movies from 90s). The famous one-liner that the hero says is that, in duels, people who are calm and take their gun slowly have a higher chance of shooting the target correctly. So, taking a gun out faster doesnt necessarily mean that one will win... I will follow that approach...

Mad Max said...

@ Mindframes: The cost issue is not monetary gains...it could be emotional costs also...buying all the tickets...that was reallyyyy smart...it is quite possible and honestly I did not think of that when constructing this example...

point on good movie liked by many not being good for others is well taken...as mentioned in the example it is but one rule for selection...

The second point I think is either from The Unforgiven or from The Good, The Bad and The Ugly (not sure which though). From your argument speed and who takes the gun out first seem to be correlated...but that might not be true...for instance we know that certain gun fighters can draw in a flash while others cannot, but ex-ante, you are unaware of how the other person will react at a given point in time...therefore the argument given in not clear...being generically fast does not mean that you will always wait for the other party to draw...it is a question of asymmetric information...you never know when the other party might be faster...

So if you were say Crazy Horse, what is your strategy, go first or respond to Sitting Bull?

The previous post was selecting crappy movies and your post explained it in detail.
Madmax- you have amazing imagination power dude..

bumblebee said...

I prefer being shot to being lynched.. For movies, I'd do the ratings online, and if I didn't have that opportunity, I'll go with my gut instinct (also by who the cast is)

Survivor said...

Do you lead or do you follow?

When it comes to movie selection,I guess I will buy the tickets for the movie that I like and convince my husband that he likes it too..:-)I will not wait for others to make my decision. I would choose the movie as I am sure I know my husband's taste.

Yes, what Mindframes referred to was from "Unforgiven". I would take the risk of getting lynched than dying. I will shoot the guy, get lynched and recover. Success never comes without some risk. So,once again, I think I will lead.

@ Madmax,
If your question was meant to be a statistical, probability etc problem...I would like to lead the comments section by answering without any mathematical equations...:-) PEACE - Survivor.

@ Saradha: I take that for a compliment... But at the same time, I was not thinking about the previous post when I wrote this one.

@ Bumblebee: So effectively you would rather follow than lead. Fair enough

@ Survivor: Again the main point of interest is that you would rather shoot than follow. However, when i said lynching, i meant a summary execution by the townsfolk. So getting lynched here implies imminent death through torture.

And no probability blah blah here. This was just a basic thing that came to mind. I have met several people who told me they will prefer to lead rather than to follow. However the question is are there situations where following might be more rational than leading.

So I guess this is just to elicit the thought process of people who choose to respond. Thats all. :-)

Manohar said...

Since your criteria seems to imply that I can't collect any information about the movies in situ... i'm assuming I can't get any implied information from the title of the movie either.
With that assumption, I will take the risk and head to the movie that has the least line. (Here again I'm assuming that everybody has just about the same level of lack of information as I do).

As for the gun fight.. I need your definition of 'too early'. Since its impossible to draw simultaneously.

Mad Max said...

@ Mano: Well I think you missed one of the key elements. One way of choosing is to herd behind others. It is quite possible that equal number of people move towards each movie and still you could end up without a ticket. Therefore another possible strategy is to randomize among the available movies.

Well "too early" implies that either gunman should signal his intention to go for the draw...for instance you can think about a flinch from one of the fighters as a signal that he is going for the kill. Hence both can flinch and theoretically draw at the same time.

BrainWaves said...

Based on my minimal WWW watching, I think someone should signal right?
If someone did not signal where is the question of drawing the gun early?

As I read it, first part is just a warm-up to second part. In otherwords, if 50 uninformed people are queuing up for ticket, it would be foolish to follow unless the girl (or "interesting" person) is standing in the queue. (I know I know.. it is our anniversary!!)

In my case, if I have so little information my decision is very easy. Since even with all the information (i.e. watching the film earlier), it is tough to convince my lovely wife :)

Mad Max said...

@ Brainwaves: Spot on my friend. The signal could be in the form of a flinch or something. Hence some signal should be there. But the question is timing the signal or actually even giving the signal yourself can be a good move.

foolish to follow unless the "interesting" person...now that sounds "interesting"...how do we ensure that she is single and available???
