The article discusses the issue of the departure from examining real behaviours in a real environment, a trend in social psychology which has been observed going back several years, and the impact of this phenomenon for social psychology as a scientific discipline. The article presents two studies on the well-known and explored “bystander effect” (Darley, Latane, 1968). This phenomenon is examined in two ways – once by way of a “traditional” field experiment conducted in natural conditions, and once through a survey. As it turned out, the results generated by the two studies were diametrically opposite, and only in the field experiment were we able to achieve a pattern of results consistent with those in the original studies.

The paper presents an account of the successful intentional introduction of the mountain species Biscutella laevigata to a lowland locality, as a result of field experiment - biological management at the toxic “Dołki” washery spoil heap (Lead and Zinc Ore Main and Factory) ZGH “Orzeł Biały” (Upper Silesia – Southern Poland). The aim of the presented study was to test the effectiveness possibilities of using the blend of seeds including a metallophyte – Biscutella laevigata seeds. The introduction of Biscutella laevigata was a part of an experiment which began in 2009-2010 with plots on the "Dolki" washery spoil heap. The tested seeds of Biscutella laevigata were examined for germination, growth and development in sites highly polluted with heavy metals. Biscutella laevigata appeared on two experimental plots. After 4 years there were numerous individuals of Biscutella – dozens of plants in various stages of development and phenology. Development of a Biscutella population from year to year (2 plants in 2010 – 58 plants in 2014) is larger and tends to increase. Biscutella individuals are spreading outside the designated test plots. The obtained results indicate that on sites highly polluted with heavy metals it is possible to perform a successful introduction of Biscutella laevgata population (increase from 2 individuals in 2010 to 58 individuals in 2014) from seeds. These results are also promising in terms of application as a new reclamation method.
