I wonder how that could be tested ?

Make the home audience cheer for home team penalties and boo for opponent penalties and measure the outcomes maybe?

  Does Philadelphia have a soccer team?

    They do! Kevin Durant is one of the owners.

You’d need to make the referees blind to which team’s stadium was home. My best shot: blindfold the referees, put them in cars, drive them to random stadiums (of teams they have never refereed and have never seen the inside of - so preferably in a different country)*, put noise-cancelling headphones on them and dress all fans in white shirts. * or use a different stadium but fill it with more home than away supporters? But then perhaps the home effect relies on it being the home stadium.

  Um, any professional referee that cannot tell what stadium they are in clearly are not familiar enough with the sport to be a referee

Have the games scored by impartial evaluators who know the rules well. This should work well, provided the games are recorded on video anywhere.

  For best results you'd need special video with several fixed vantage points, not video that follows the ball or the refs' attention.

    Every professional sport in America has this specifically for coaching and analysis, so I can't imagine that the top-tier European leagues (at minimum) don't have access to something similar.

      The Premier League requires 20-30 cameras depending if it's being broadcast live or not. Appendix 3 (page 497) has detailed specifications on what type of cameras go where in the ground and what they should be pointing at, etc. https://resources.premierleague.com/premierleague/document/2020/09/11/dc7e76c1-f78d-45a2-be4a-4c6bc33368fa/2020-21-PL-Handbook-110920.pdf https://resources.premierleague.com/premierleague/document/2...

    Even with imperfect video, any errors would not be biased towards any team.

I bet you can get most of the answer by checking for changes in two stats that can be empirically calculated: # of ground tackles and # of true offsides. Both could be algorithmically done provided decent footage.

  Offsides decisions can be pretty controversial, even with video-ref. Not to say you couldn't measure most of them reliably, but it's not trivial.

You could have referees who aren’t in the stadium with the fans making the calls? Basically a squad of Larry Middleman[1] & George Bluth referees. [1]https://arresteddevelopment.fandom.com/wiki/Larry_Middleman https://arresteddevelopment.fandom.com/wiki/Larry_Middleman

Compare with “home” games that aren’t really home games? For example, Manchester City had a home game in Budapest this year (https://www.bbc.com/sport/football/56343751 https://www.bbc.com/sport/football/56343751) Clubs also sometimes are banned from playing in their own stadium, or can’t play there because it is being renovated. Another idea: look at Inter Milan versus AC Milan or Genoa vs Sampdoria matches. Those clubs share a stadium, so they play their away games in their home stadium and vice versa. You could also look at players who, after a decade or more at a club, switch clubs and soon thereafter return to their former home stadium to play an away match (yes, yet another confounding factor, and such players are extremely rare in today’s football)
