The bigger story

Prediction and experimentation

Football prediction is hard. That is exactly why it is a useful place to show how analytics should work: transparent enough to question, simple enough to start with, and flexible enough to grow with new evidence.

Whether for the World Cup or for your business, a prediction is valuable when you can understand it, test it, and improve it.

The journey

From curiosity to your own model

PiPredict shows how a prediction can begin modestly and improve over time. Each step uses Panintelligence to make the thinking visible, so users can decide what they would keep, remove, or weight differently.

01

Ask a better question

Instead of asking who will win, start by asking which signals might explain team performance and where uncertainty still lives.

02

Build a trusted foundation

Use governed historical match data, clear assumptions, and repeatable measures that can be explained to other people.

03

Make the model visible

Expose the drivers behind the prediction with Panintelligence's Analytics Chart, so users can see why the model leans one way.

04

Improve after every game

Each result becomes a new story: what changed, what surprised us, and which assumptions should move next.

Step one

Start with the data, then decide what matters.

We began with historical international football results and used Panintelligence to turn raw outcomes into explainable signals. This is the foundation users can inspect before creating their own prediction logic.

Raw Data

The model starts with an extensive dataset of historical international football matches. The raw data is continuously updated and sourced from the international_results GitHub repository.

This gives us a shared foundation: match outcomes, scores, and enough history to begin asking which patterns might matter.

From Data to Insight

Panintelligence Analytics helps identify which engineered fields are most influential in historical match outcomes. Those signals become a starting toolkit for the Team Strength Index.

The important part is not that our weighting is perfect. It is that the weighting is visible, explainable, and open to challenge.

Your model can be different

Maybe you care more about defensive resilience. Maybe recent form should fade faster. Maybe home-continent advantage deserves a place. Panintelligence gives users a way to test those instincts against the data instead of guessing in the dark.

Step two

See why the model thinks what it thinks.

The Sankey Decision Tree below comes directly from Panintelligence. It shows how match scenarios flow through the strongest signals and where those decisions lead.

Find the first split

What does the model reach for before anything else, and does that match your intuition?

Follow the thickest path

Volume matters. A convincing rule is more useful when it applies to enough matches.

Look for fragile rules

Some paths look exciting but rest on smaller samples. Those are places to question, not blindly trust.

Step three

Create your own strength index.

The Panintelligence Team Strength Index (PI-TSI) combines pre-match evidence into three simple scores: Form, Attack, and Defence. It is designed to be clear enough for users to debate and adapt.

  • Form: how recent results shape momentum.
  • Attack: how consistently a team creates goals.
  • Defence: how well a team limits opponents.

Team Explorer

Compare teams, inspect the components, and decide where your prediction would diverge.

Step four

Test your assumptions group by group.

Group tables let users move from abstract team strength into tournament context. This is where a prediction starts to become a story about routes, pressure, and trade-offs.

Our first attempt

PiPredict gives us a view, not a verdict.

The first simulation is a working example of the process: transparent inputs, explainable rules, and a result users can challenge. The value is in the conversation it starts and the improvements it invites.

What the model uses

PI-TSI uses pre-match evidence: recent results, goals scored, and goals conceded. These are converted into Form, Attack, and Defence, then combined using factor importance identified by Panintelligence Analytics.

What it does not claim

It does not remove uncertainty, read team news, simulate cards, or know how pressure will change a match. Those gaps are not embarrassing; they are opportunities for users to make a stronger version.

Reference simulation

A bracket to challenge, not a winner to worship.

This bracket shows how our current PI-TSI scores move through the World Cup 2026 structure. Treat it as a baseline: if your assumptions are better, your bracket should be different.

Loading tournament bracket...

* Knockout progression follows the official FIFA 2026 match-number path. For example, M89 is W74 v W77, so adjacent Round of 32 cards do not always feed into the next visible row.

How this simulation works

The simulation uses PI-TSI to evaluate match outcomes. In the group stage, teams receive 3 points for a win, 1 for a draw, and 0 for a loss.

If teams finish level on points, the simulator ranks them by head-to-head points, head-to-head goal difference, head-to-head goals scored, overall goal difference, overall goals scored, PI-TSI score, then team name as a stable final fallback.

The top two teams in each group qualify automatically. The eight best third-placed teams also advance, ranked by points, overall goal difference, goals scored, PI-TSI score, then team name. Once those eight groups are known, the official FIFA allocation table maps them into the Round of 32 slots.

FIFA's full rules also include team-conduct and world-ranking fallbacks. This model uses PI-TSI instead because it does not simulate yellow or red cards, keeping the prediction transparent and explainable.

The learning loop

Every result is a chance to improve the model.

As the tournament unfolds, PiPredict can compare expectation against reality, highlight surprises, and give users a fresh reason to revisit their own assumptions.

What did we miss?

Look for teams whose performances break the current weighting and deserve a new signal.

What became clearer?

Some assumptions will get stronger as evidence grows. Others should fade.

What would you change?

The strongest outcome is a user who can explain why their prediction should now beat ours.

Our second attempt

Reality gave the model a useful objection.

V1 was not a failure to hide. It was the first version of the story: a transparent PI-TSI prediction that could finally be tested against real World Cup results. Once those results arrived, they showed us two things at once: the model needed a stronger signal, and the tournament matches had to stay out of the training data.

Freeze the evidence

World Cup 2026 matches were flagged as wc2026 = 1. The model can compare against those results, but the training view excludes them.

Add an outside signal

FIFA points difference was added from the ranking snapshot before the tournament began, so it represents pre-tournament strength rather than leaked match evidence.

Keep the first answer

V1 remains visible as the baseline. V2 is the next attempt beside it, so improvement is measured instead of rewritten.

What changed

The decision tree found the missing signal.

When the decision tree was rebuilt with the cleaner training set, FIFA points difference dominated the model. That does not make form, attack, or defence meaningless. It says the strongest split in this version came from the gap between how strong the teams were rated before the World Cup started.

0.93 FIFA points difference

The dominant signal in V2, carrying most of the model weight.

0.02 defence difference

A smaller supporting signal from the original PI-TSI thinking.

0.02 tournament type

Match context still contributes, but no longer drives the prediction.

0.01 form, attack, neutral

Each remains useful, but the tree no longer reaches for them first.

V1 vs V2

The point is not perfection. The point is measurable improvement.

Both versions are now compared against the same real World Cup results. The interesting story is not that V2 is suddenly perfect. It is that a clear new signal made the prediction better while preserving the evidence trail from the original attempt.

V1 baseline: 4 / 12

The original PI-TSI model correctly predicted 33.3% of winners across the matches already played.

V2 second attempt: 7 / 12

After adding FIFA points difference, winner accuracy rose to 58.3% for the same comparison set.

Exact scores: 2 vs 1

V1 still has more exact scores, which keeps the comparison honest and more interesting than a single headline metric.

What V2 is really saying

The second model is not claiming that rankings are everything. It is saying that once real results started challenging the first prediction, the strongest missing pre-tournament signal was FIFA points difference.

That is the story of PiPredict: build the first version, compare it with reality, protect the training data, and let the next version explain exactly what it learned.

The next loop

The second attempt becomes the next baseline.

V2 improves the winner prediction so far, but it also creates the next question: if FIFA points carry most of the signal before the tournament, when should live tournament form start to challenge that assumption?

Hold the line

Keep FIFA points frozen before the tournament, so the model does not learn from the results it is being asked to predict.

Version the next idea

When the model changes again, we will keep V1 and V2 visible. The journey matters because each version can be explained, tested, and compared.

Second Attempt Added

The first real World Cup results gave PiPredict something useful to react to. We flagged tournament matches as wc2026 = 1, kept them out of the training view, and added FIFA points difference as a frozen pre-tournament signal.

That second version improved winner accuracy from 4 / 12 to 7 / 12 for the matches already played, while keeping V1 visible as the original baseline.
