Personality assessment
A 20-question Mini-IPIP was done (Donnellan et al., 2006), created on the basis of the 50-question "International list of personality traits" L. Goldberg (Goldberg, 1999).
Big five:
- Extroversion: this feature includes such characteristics, how excitability, sociability, talkativeness, self-confidence and a lot of emotional expressiveness. High levels of this trait are associated with a large number of friends., higher life satisfaction and lower rates of mental disorders.
- Agreement: this dimension of personality includes such attributes, how trust, altruism, kindness, attachment and other prosocial behavior. This measurement is a good predictor of job choice.: acceptable people tend to choose professions, which include caring and nurturing behavior, low competition, for example, nurse, Therapist, Teachers, charity worker or doctor (excluding surgeons). People with low consent, usually, love competition and choose a profession, which require less compassion, such as CEO, lawyer, journalist, policeman or chef. Consent also predicts political views, since nice people tend to be liberal or leftist, while failing people are conservative or right.
- Good faith: common features of this dimension include a high level of brooding, good impulse control and purposeful behavior. They, who value conscientiousness, tend to be organized and attentive to detail. This trait is good at predicting academic and work success..
- Neuroticism: people, high-handed, tend to experience emotional instability, anxiety, capriciousness, irritability and sadness. High scores for this measurement are often, but not necessarily, associated with anxiety disorders and depression.
- The grades of this sample were compared to a larger sample of college students., used to check this individual questionnaire.
- Extroversion, medium: 2.67, SD: 94, interpretation: low.
Agreement, medium: 3,46, SD: 87, interpretation: low. Good faith, medium: 2.99, SD: 81, interpretation: low. Neuroticism, medium: 2,93, SD: 83, interpretation: high. Openness, medium: 4,03, SD: 73, interpretation: high.
Means and standard deviations for the large five personality scales, interpretation (low or high) compared to the reference sample. All differences are statistically significant with mean effect sizes.
Nootropics: use and perception of effects
Participants tried different substances step by step, everything was 63 substances (with nootropic effect). If the participant noted a nootropic effect, then later he was asked to describe the alleged effects after taking this substance.
Perceived Effects
All perceived effects were rated on a seven-point scale.. The following charts summarize the results. Substances are indicated on the Y-axis, highest to lowest average. The dots indicate the average rating for that substance.. Lines indicate 95% confidence interval (CI), thus expressing the uncertainty of the corresponding mean. Broader CIs indicate more variability in responses. The red line indicates a neutral response with the words "no effect". Usually, all average ratings with confidence intervals, crossing the red line, probably, will have no effect. If the bottom (left) end CI above, how, for example, white line for "small magnification", the effects of this substance were estimated to be quite high. It rarely happened. Most substances had ratings somewhere between "no" and "little effect", with some exceptions.
Evaluation of the "pleasantness" of the effect
Most substances were rated somewhere between neutral and mildly pleasant., which indicates, that negative effects are rare for nootropics. Three substances were rated as neutral, but the confidence intervals are extremely large. On the other hand, some substances were rated as more "slightly" pleasant: DMHA, Huperzine A, Selegiline и LSD.
Anxiety
According to answers, anxiety is most effectively reduced by the following substances: L-theanine, thianeptin, CBD, coffee and phenibut.
