"to su take studie..." sorry, ale tieto tvoje krcmove mudrosti bez ziadnej realnej skusenosti nezneju o nic serioznejsie.

myslis, ze brankari netrenuju reflexy?

s tou poslednou vetou sa da rozhodne suhlasit.

In soccer penalty kicks, goalkeepers choose their action before they can clearly observe the kick direction. An analysis of 286 penalty kicks in top leagues and championships worldwide shows that given the probability distribution of kick direction, the optimal strategy for goalkeepers is to stay in the goal’s center. Goalkeepers, however, almost always jump right or left. We propose the following explanation for this behavior: because the norm is to jump, norm theory (Kahneman, D., & Miller, D. T. (1986). Norm theory: Comparing reality to its alternatives. Psychological Review, 93, 136–153) implies that a goal scored yields worse feelings for the goalkeeper following inaction (staying in the center) than following action (jumping), leading to a bias for action. The omission bias, a bias in favor of inaction, is reversed here because the norm here is reversed – to act rather than to choose inaction. The claim that jumping is the norm is supported by a second study, a survey conducted with 32 top professional goalkeepers. The seemingly biased decision making is particularly striking since the goalkeepers have huge incentives to make correct decisions, and it is a decision they encounter frequently. Finally, we discuss several implications of the action/omission bias for economics and management.

tej uruguajec co sa rozbiehal 20 metrov, to som uplne vedel, ze to da do hladiska.
a ten ghanan, co to kopal z miesta, to bola jasna placirka do rohu.
vela zalezi na tom, ako sa hrac rozbieha, brankari merkuju penalty hracov z inych zapasov atd..
stat v strede je rozhodne kokotina. :D
