Autopsy The Stats Don’t Lie: VicBIAS By The Numbers - An Empirical Analysis

Do you agree there is inherent umpiring bias toward Vic based teams?

  • I barrack for a Vic based team: Yes, always has been, always will be. Suck it up.

  • I barrack for a Vic based team: Yes. It’s a disgrace. I demand a fairer comp.

  • I barrack for a Vic based team: No. It’s a myth. Stats are the work of the devil.

  • I barrack for a non-Vic based team: Lol. Tell me something I don’t know.

  • I barrack for a non-Vic team: I like to cry about anything to do with the AFL because they are just

This gentleman has broken down umpire bias in terms of home and away teams, in particular looking at the difference between Vic teams v non Vic teams both at home and away.

The stats speak for themselves.


Have posted a poll to get views, but in the interest of being true to the analysis have framed the poll on a similar basis.

Are all South Australians sooks or just the ones on Bigfooty??

The VFL expanded and let some interstate clubs join, and all you want to do is whinge about it. Don't like the league? Simple, go watch the SANFL.

Mobile phone screenshot. Must be true.
I would like to see it verified. But if it is true something needs to change.
WC and Sydney are the only non Victorian sides to win a flag since 2006 and you could argue both were lucky and less than a goal in both games could mean no flags was a statistical possibility.

With 18 teams and growing, the longer this goes on the less non Victorian side eyeballs will invest in this sport.
 
Was unfair umpiring an outcome of the 2007 AFL investigation into non Victorian flags?
For 2024 until 2040 should the AFL reverse their direction to umpires and make it unfair to Victorian sides?

2017 grand final. Cotchin not getting suspended for big hit to Shiels head in the 2017 preliminary final.

Surprised this type of idiocy took 29 posts.

That doesn't verify his claim one way or another.

Great input.

I don't know if this is a nuanced point or not but one thing I get frustrated about with any discussion around free kick numbers is an analysis of whether the free kicks are there or not, and I guess you could say the free kicks that weren't paid.

The assumption of people who talk about free kick numbers as a differential without any context is that the free kicks were either unfairly paid or other ones were missed. But this is just that, an assumption.

If you actually want to objectively prove the point that free kick decisions are biased towards one team or another, you'd had to go through every game over that 8 year period, assess each contest according to the letter of the law, and decide if a free kick should or shouldn't have been paid according to the letter of the law.

But we know that's unrealistic and unfeasible, that the adjudication of this sport is easily the most complex in the world, where there are a myriad of factors that determine whether a free kick will be paid i.e more free kicks earlier in a season, putting the whistle away towards the end of close games, changes in the interpretation before and during a season, the positioning of the umpires and also the coaching of players in tackle technique, fitness and discipline to not give away free kicks. Never any talk of teams giving away dumb free kicks, it's always some deeper conspiracy

To say that a free kick differential alone is evidence of bias towards one team or another is a logical fallacy and completely bonkers. It's bottom of the barrel, one eyed football jingoism.

Yes it's a good way to measure coin tosses and that's about it.
 
My observation from watching AFL since the Crows joined the comp is that for a non Vic team playing against a Vic team in Vic, the issue with the umpiring isn’t so much the frees that get paid to the home Vic side, but the frees that don’t get paid that should have to the non-Vic side.

there is minimal consistency favouring the home Vic side.

I would argue the incorrect decisions you are referring to would predominantly fall into this category, thereby effectively being embedded in the analysis presented.

here is a classic exception though, absolute beauty of a decision:

Same thing happens when teams play away in Adelaide, Perth, Brisbane and Sydney - in fact it's worse because those teams get 10 genuine home advantage games a year vs around 4-6 for Vic clubs.

In other words, sook harder 🙄
 
Im still waiting for someone to post up a Vic v non Vic free kick count that shows 1 umpire giving 50% of total free's in a game to a non Vic side as happened to Port v Cats or Crows V Dogs.


Here's the link, easy to find


ADELAIDE spearhead Josh Jenkins believes "90 per cent" of the free kicks paid against the Crows were correct despite the lopsided count in Saturday night's Western Bulldogs-Adelaide clash. The Crows were on the wrong end of a 28-12 free kick tally in their 15-point loss at Etihad Stadium, with 16 more frees going to the home side.

Adelaide coach Don Pyke last night said the club would seek further clarification from the AFL umpiring department about some of the decisions made during the game.

How could no flags be a statistical possibility? Had the results in those games been reversed an interstate team still would have won 😂

What about the 15 years before 2006 how many interstate teams won the flag then? 92, 94, 97, 98, 01, 02, 03, 04, 05, 06 - oh wow looks like a lot of interstate sides winning flags, I guess Vicbias didn't exist between the years 92-2006?

The sooking is hilarious especially when you consider some all time teams have won flags since 2007 - Cats, Hawks and Tigers sharing 11 flags between them.

This is the dumbest argument. Melbourne have left Victoria 4 times this year. So we get 10 genuine home games vs demons 19 games in Victoria. I'd take 19 games in South Australia vs 10 "genuine home games".

What are you talking about? We've left Victoria 8 times this year plus playing in Geelong.
