[Verse 1]
Sarah sees the market crash on Tuesday morning news
Panic selling everywhere, red numbers make her blues
But wait - she holds her cursor still above the trading screen
What's my prior probability? What does this chaos mean?
[Chorus]
Start with your baseline, then adjust with care
New information floating everywhere
Don't let the vivid stories twist your mind
Bayesian updating - measured and refined
How much should this evidence really shift your view?
Base rates anchor you to what is true
[Verse 2]
A trader spots the protest crowds marching through the street
Cameras capture angry shouts, drama burns like heat
Organic rage or orchestrated? Headlines scream so loud
But priors whisper quietly above the roaring crowd
[Chorus]
Start with your baseline, then adjust with care
New information floating everywhere
Don't let the vivid stories twist your mind
Bayesian updating - measured and refined
How much should this evidence really shift your view?
Base rates anchor you to what is true
[Bridge]
That shocking anecdote feels like the smoking gun
But one vivid story doesn't outweigh ten thousand, son
The formula is simple but the discipline is hard
Multiply your prior by the evidence regard
[Verse 3]
Most folks swing too wildly when the headlines catch their eye
Abandon their assumptions when emotions running high
But contrarian analysts know the secret sauce
Weight the new against the old, calculate the cross
[Chorus]
Start with your baseline, then adjust with care
New information floating everywhere
Don't let the vivid stories twist your mind
Bayesian updating - measured and refined
How much should this evidence really shift your view?
Base rates anchor you to what is true
[Outro]
Prior times the likelihood divided by the whole
Keep your reasoning steady, that's the analyst's goal
