The study deals with the issue of misleading information in the Internet environment. The authors define and analyse basic terms denoting various methods of disinformation. They point to the fact that there are specific terms and phenomena forming the thematic axis of the current discourse on disinformation practices in online media. They state that there is quite a lot of chaos in the field of terminology. This is the reason why they critically reconsider the existing knowledge related to disinformation, such as fake news and the like. The ambition of the authors is the conceptualisation of disinformation methods in the context of a broadening of genres and social background. They emphasise the need to research the issue because the information quality of various blogs, posts, comments, etc. raises many unanswered questions or incorrect answers. In their analysis of the issue, they use the basic methods of logical analysis, the hermeneutic approach, as well as selectively chosen examples of individual typological variants of disinformation.

The article presents problems related to life quality, life satisfaction and sense of happiness, their determinants, methods of measurement and dependence on the level of wealth and other conditions. Life quality is an abstract blurred term which depends on numerous factors. There is not any single, comprehensive definition, measure or cause of such phenomena as life quality, economic well-being or sense of happiness. Their evaluation depends on economic, political, cultural and social conditions and also on individual features, expectations and attitudes. More and more often, next to hard economic coefficients, social indicators are applied, and synthetic measures of the level of life quality or social and economic well-being are developed. The level of social development is strongly affected by the quality of human capital. The article presents an attempt at matching parameters and indicators which characterise various aspects of life quality and applying them for the development of synthetic measures of life quality in its different aspects. It is also aimed at comparing them with the current results obtained by research studies in this field. The aim of the article is to provide an assessment of diversification in the levels of living conditions observed in some selected countries – its size, specificity and cause-effect relations with the use of the listed parameters and measures. The research on life quality should be applied to the assessment of the efficiency of social and economic policy which has been currently implemented.
