“…That is, we observe that the titles of roughly every fourth study include a reference to the concept of competitive balance and the resulting match outcome uncertainty. Interestingly enough, these references are surprisingly diverse, and include, for example, championship uncertainty (e.g., Pawlowski & Nalbantis, 2015), competitive intensity (e.g., Bond & Addesa, 2020), loss aversion (e.g., Besters et al, 2019), outcome uncertainty (e.g., Martins & Cró, 2018), uncertainty (e.g., Serrano et al, 2015), uncertainty of outcome (e.g., Hogan et al, 2017), and uncertainty of results (e.g., Cox, 2018). 25 Further, as the debate on the validity of Rottenberg's (1956) so-called uncertainty of outcome hypothesis has not yet been laid to a final rest, we note a relatively consistent output of such studies in the last decade; that is, in 2010 (3), 2011 (1), 2012 (4), 2013 (4), 2014 (2), 2015 (4), 2016 (2), 2017 (1), 2018 (4), 2019 (2), and 2020 (3).…”
