Bayes’ theorem is probably the single most important thing any rational person can learn.
So many of our debates and disagreements that we shout about are because we don’t understand Bayes’ theorem or how human rationality often works.
Bayes’ theorem is named after the 18th-century Thomas Bayes, and essentially it’s a formula that asks: when you are presented with all of the evidence for something, how much should you believe it?
Bayes’ theorem teaches us that our beliefs are not fixed; they are probabilities. Our beliefs change as we weigh new evidence against our assumptions, or our priors. In other words, we all carry certain ideas about how the world works, and new evidence can challenge them.
For example, somebody might believe that smoking is safe, that stress causes mouth ulcers, or that human activity is unrelated to climate change. These are their priors, their starting points. They can be formed by our culture, our biases, or even incomplete information.
Now imagine a new study comes along that challenges one of your priors. A single study might not carry enough weight to overturn your existing beliefs. But as studies accumulate, eventually the scales may tip. At some point, your prior will become less and less plausible.
Bayes’ theorem argues that being rational is not about black and white. It’s not even about true or false. It’s about what is most reasonable based on the best available evidence. But for this to work, we need to be presented with as much high-quality data as possible. Without evidence—without belief-forming data—we are left only with our priors and biases. And those aren’t all that rational.
NUTRIENTS FOR YOUR EYES

A thread
As the year comes to an end, it is important to reflect—“To finish what we start takes hard work, wisdom, self-discipline, and patience. Anyone with vision can start a big project. But vision without wisdom will result in unfinished projects and goals.”
There is a severe lack of a thorough understanding of the fundamentals of redemption in The Body of Christ.
Until believers understand certain dimensions of God holistically, they will never be able to rise sustainably in the Kingdom of God.
Understanding the fundamentals of Christ's redemption serves as a proper foundation for the believer.

@ShehuSani This is a reflection of lack of accountability in our political landscape. To drive meaningful change as a nation, we must all embrace the culture of accountability and embrace transparency.
But He was wounded for our transgressions, He was bruised for our iniquities; The chastisement for our peace was upon Him, And by His stripes we are healed. (Isaiah 53:5 NKJV)
@DrTedros@WHO It's disheartening to see the lack of commitment to #EndMalaria in sub-Saharan Africa. One possible reason for this is the financial gains some individuals or organizations make from the persistence of this problem.
@qrsupport Wow, I'm pleasantly surprised that you responded to this tweet! I understand that being called out can be uncomfortable, but I appreciate your willingness to engage nonetheless. As requested, I'll send you the details.
Consider avoiding @qatarairways as much as possible. Despite sending numerous emails requesting a refund, they have refused to issue one. Unfortunately, my first experience with this airline has been regrettable.
In the event of an opposition party's triumph in Lagos, an extensive exposé of corruption is anticipated to surface. The extent of this discovery would render Abacha's looted assets insignificant in comparison. #OppositionWins#Lagos#Corruption#Abacha#Politics
After analyzing the logistical challenges of the 2023 Presidential & NA elections, it is sad to note that over 400 billion naira was expended to conduct the general election in Nigeria. #INEC must be held accountable for their stewardship of the funds allocated for this purpose.
It is unequivocally disgraceful that the INEC chairman persists in denying his apparent ineptitude in executing dependable elections, as evidenced by the fact that election results have yet to be uploaded even after two days since the polls were conducted. #NigeriaDecides
@ChelseaFC Hiring ‘an unknown’ coach and dismissing a Champion League winner was a flawed decision, and the reckless actions of the board are now causing negative consequences.
