  Most decision-making models, including the pairwise comparison method, assume
the decision-makers honesty. However, it is easy to imagine a situation where a
decision-maker tries to manipulate the ranking results. This paper presents
three simple manipulation methods in the pairwise comparison method. We then
try to detect these methods using appropriately constructed neural networks.
Experimental results accompany the proposed solutions on the generated data,
showing a considerable manipulation detection level.
