An increase in morbidity and mortality due to COVID-19 in 2020-2022 has forced various countries to introduce lockdowns. Due to unfavorable economic consequences, this measure often caused a negative attitude toward the population, leading to sabotage and even protests. In this study, we question whether it is possible to change the population's attitude towards lockdown by emphasizing economic loss prevention. Based on the results of an online survey of 23,064 residents of Russia, we show that mentioning the negative economic consequences of a lockdown reduces the level of support for it. In contrast, mentioning the possibility of avoiding long-term negative consequences for the economy reinforces this support. The influence of economic loss prevention treatment holds for the poor and people with full-time employment, although these are groups that the lockdown can affect in the first place. Moreover, we show that economic loss prevention treatment can even influence people's opinions who were initially firmly against the lockdown. However, loss prevention treatment is not significant for people who have already experienced the pandemic's direct negative economic consequences.
