This  study  aims  to  examine  the  effects  of  dark  patterns,  designed  using  cognitive  biases  and persuasive  technologies,  on  users'  attitudes  and  behaviors  through  the  perception  of  urgency  and scarcity. To achieve  this  objective,  the  formation  process  of darkpatterns  was  thoroughly  analyzed, starting  from  the  physical  and  structural  transformations  in  graphical  user  interface  designs  and extending   to   all   related   aspects.As   a   result   of   this   analysis,   the   ethical   framework   of persuasiveness—one  of  the  most  critical  qualities  of  good  design—has  been  investigated,  and persuasive  designs  that  exceed  these  ethical  boundaries  have  been  identified.  The  study  examines designs in line with a universal ethical perspective and explores the extent to which users are exposed to dark pattern techniques that manipulate their rational decision-making processes. Findings  from  the  study  indicate  that  nearly  all  participants  have  encountered  dark  patterns  that create   a   sense   of   urgency   and   scarcity   across   multiple   platforms.   While   dark   patterns   are predominantly   experienced   on   websites   and   mobile   applications,   participants   also   reported encountering   them   on   gaming   consoles,   television,   newspapers,   store   displays,   and   printed publications.  Participants'  perceptions  regarding  the accuracy  of  information  presented  within dark           patterns were assessed, revealing an overall tendency toward uncertainty. The subsequent tendencies were disbelief in the accuracy of the information, followed by eventual belief.When  evaluating  the  influence  ofdark  patterns  that  create  a sense  of  urgency  and  scarcity  on participants'  decision-making  processes,  the  findings  suggest  that  the  majority  of  participants  were affected in their decision-making. In this context, the necessity of raising user awareness against dark patterns—the  core problem  this study addresses—has  been quantitatively  supported by  the  research findings.
