SECTION 2. COMMON MISTAKES IN DEALING WITH RNG
If you frequent WoW economic blogging sites and forums you may have seen the term ‘freetard’ come up.
This is a pejorative term used to refer to people who, being ignorant of opportunity cost (link), mistakenly believe that if they farm materials themself the item is free of cost. Here I’d like to expand on this and demonstrate how a poor understanding of chance can, and does, frequently lead people to waste ridiculous amounts of time.
I’ll also share many stories of frustration born out of these situations. (RNGtard)
MISTAKE #1 – ASSUMING THAT RANDOM IS FAIR
“Random does not remember, and random does not care”
Random does not equal fair. If an item has a 10% chance of dropping then probability states that it should take ten kills to see the item drop once. In practice this will not be the case for everyone. Some people will see the item drop ten times from ten kills and some people will not see the item drop at all in twenty kills.
This is completely normal. This is what random means.
People often make the mistake of assuming that ‘random’ means ‘fair and even distribution’. If I flip a coin 10 times and get 10 heads it’s not a sign that something is broken – it’s a sign that random is working as intended!
MISTAKE #2 – ASSUMING THAT RANDOM REMEMBERS
Past random events do not influence future ones. If you were unlucky enough to kill a boss 20 times for a 10% drop, and didnt get it, then on your 21st time killing the boss your chance of getting the item is….exactly the same as it always was at 10%.
If you’re farming a 1% drop, for example the Baron’s Mount, then statistically it should take 100 kills to see 1 drop. The odds of it dropping remain the same, however, no matter if it’s your 1st kill or your 100th kill.
MISTAKE #3 – MISCALCULATING OR IGNORING THE ODDS OF AN EVENT
This one absolutely kills me. People who choose to ignore statistics and probability at the cost of their time. I can’t tell you how many times over the years I’ve cringed at hearing what someone was ‘farming’ – let me make a few honorable mentions:
A guy farming a very specific area and creature for a world drop item. Having checked wowhead for where it dropped and seeing every single creature of a specific level on the ‘dropped by’ table he proceeded to go and farm the one that dropped it .00002% of the time over the one that dropped it .00001% of the time.
A guy on the forums who reckoned that since the four items he was farming had drop rates of 12%, 15% 20% and 25% he had a 72% chance of getting at least one.
The fellow who reasoned that since he’d killed the baron 21 times so far his chances of having the mount drop soon were ‘getting better’.
MISTAKE #4 – LOOKING FOR PATTERNS WHERE NONE EXIST (TRENDS?) (SAME AS #2)
In statistics (citation needed) this mistake is also known as ‘Gamblers Fallacy’. This is the belief that in a chance based event a particular outcome may be ‘due’ based on previous outcomes. Imagine a situation in which someone flips a coin three times and gets three consecutive heads, then imagine someone saying “I’m going to call tails, because tails is due” and thats what I’m on about.
You might know people in real life who regularly gamble. Have you ever heard them say “I’m due for a big win” after a losing streak? People seem to take an almost superstitious view towards finding these patterns and insist they exist and keep wasting their money!
