  Happiness research understands "happiness" as "life satisfaction" or "well-being". Since it has proved difficult to find a definition of happiness, individual people are instead asked how happy they feel. Numerous surveys are then summarized and analyzed using static methods. Although some researchers believe that the scales are fundamentally unsuitable for estimating happiness, other researchers argue that the happiness indices formed on the basis of the survey have a high statistical correspondence with characteristics that are generally understood to indicate a happy person. For example, individuals who report high happiness on scales smile more often, exhibit more social behavior, are more helpful, and are less likely to commit suicide. For this reason, happiness indices determined on the basis of the survey are considered reliable by happiness researchers.
  
  Before recommending strategies, it is crucial to rely on rigorous, large-scale experiments that confirm their effectiveness. Over the past decade, there has been a significant shift in what constitutes 'high-quality evidence ' in psychology (there were adopted e. g. practices like pre-registration, committing to specific methodological and analytical decisions in advance, and increased sample sizes to avoid underpowered studies). A meta analysis of 2023 has used this modern evidence-based approach, evaluating evidence for common happiness-boosting strategies. The study aimed to shed light on the effectiveness of these strategies and their impact on subjective well-being. As a first step, the authors analyzed numerous media articles on happiness to identify the five most commonly recommended strategies, these were: expressing gratitude, enhancing sociability, exercising, practicing mindfulness/meditation, and increasing exposure to nature. Next, the published scientific literature was searched but limited to the above-described high-quality criteria that tested the effects of these strategies on subjective well-being in everyday individuals (non-clinical samples). Only 10% of the initially retrieved studies met those rigorous criteria. The findings revealed that unlike so far suggested by scientific studies, there is currently still a lack of robust scientific evidence to support some of the most frequently suggested happiness strategies. Among the five most common happiness strategies, there was "reasonably solid evidence" of positive effects from a) Gratitude messages or lists, b) conversations with strangers or Gratitude and sociability – that is, establishing and maintaining social relationships. In contrast, no convincing evidence could be found that c) sports, d) mindfulness training, or e) walks in the countryside make people happier.
