Have you seen evidence to the contrary re attention spans?
Yes, lots, see this post where I lay it out in detail.

Have you seen evidence the concept “attention span” abstracted from context and motivation exists as a scientifically and rigorously defined concept? In a way that is falsifiable and not just narratively connecting correlations into something that gestures vaguely at something we believe is intuitive?
-----Literally ALL of the studies you linked indicate correlation not causation.------

Although this study confirms the negative effects associated with frequent use of short video platforms, there are several limitations. First, while the study identified a relationship between the duration of short video usage, addiction to short videos, and the phenomenon of TikTok brain, along with decreased attention control, the cross-sectional design of the research prevents the establishment of causal relationships between the variables.

Finally, the cross-sectional, questionnaire-based design limited the ability to infer causal relationships or explore underlying mechanisms.

Correlation analyses revealed a significant negative relationship between MPSVATQ and self-control, in addition, a significant negative correlation was also found between MPSVATQ and the theta power difference under incongruent minus neutral target condition of the ANT, suggesting that individuals with a proclivity for mobile phone short video addiction may encounter challenges related to executive control and self-control abilities.

Short-form video media use was significantly associated with higher inattentive behaviors. The association was stronger among younger participants. No significant associations were found with hyperactive–impulsive or oppositional-defiant behaviors, although total screen time remained significantly associated with these outcomes.
Although current research methods have their limitations, the evidence suggests that frequent short-video use is associated with poorer cognitive functioning.

SVA is significantly associated with reduced attentional control, as demonstrated by studies conducted by Xie et al. (Citation2023), Ye et al. (Citation2025), Zhou et al. (Citation2024), and Singh and Prusty (Citation2025). The correlations were low to moderate in strength (r = −0.23, p < .01; r = −0.56, p < .01; β = 0.43, p < .001; r = −0.209, p = .006).

Variations in measurement tools for SVA and cognitive outcomes may also limit comparability, while reliance on self-reported video usage can introduce reporting inaccuracies.

Second, due to the cross-sectional survey design, it was not possible to determine causal relationships between SVA, IA, and negative emotions.

Given the cross-sectional design of this study, the findings should be interpreted as associative rather than strictly causal relationships.

The potential harmful consequences of frequent use of short-video platforms are revealed in this study. However, the relevant conclusions have the following limitations. Firstly, due to the cross-sectional design employed, the directionality of the associations between variables and the causal mechanisms cannot be ultimately determined.

You misunderstand this, the link to motivation has to do with how salient a particular thing is to you overrides any abstracted idea of attention span not that people “aren’t motivated enough” in general which is nonsense moralizing.
